Driver's side with the rocker molding and rear quarter molding trial fitted. Hardware for the quarter should be here soon. Hate to drill a hole in the quarter but it's always hidden and I'll POR it for now.
still need to paint the pass side window trim and the rocker areas, adjust windows and top, then assemble the interior and swap the trunk lid.
Wife is really liking the shadowline. Will trial fit the painted bumpers soon. Mtech 1 will hopefully be done in time for assembly next weekend, but I won't have the angled Strömung exhaust until end of the month. So I probably can't mount the rear until I replace the cat back.Last edited by bradnic; 09-03-2017, 06:00 PM.I BUY/SELL REFURBISHED CM5907s & CM5908s

parking this here. as a 7/90 build this car came with a mechanical convertible top. if you look at the stamping though, all the holes are there to mount the electric top gear. I do have to cut out the top motor area on the pass side, but you can see where a die insert was placed in the stamping press.
and here's an electric top car, similar view
EDIT looking for PDF hosting
I even have the installation guide here
So no way I can resist a conversion, and I already have most everything including the electric top frame and canvass, harness, motors, cables and control boxes. The top even supports a zip out window but it's missing the plastic window. It's not in terrific shape though so I'm looking into getting an OEM top. If I can find a reasonably priced aftermarket zip in window I may go that route for a while to just to get the project going.Last edited by bradnic; 09-03-2017, 05:24 PM.I BUY/SELL REFURBISHED CM5907s & CM5908s

I ended up buying new trim because the channel for the other clips got brittle and broke but those end clips can be reused. They just cannot be bought on their own.

Car is not converted from electric - the oblong hole for the top motor is not stamped out. You can clearly see an outline for it though, which is not present on earlier DB verts. That outline is there because the stamping tooling was modified with an insert. Once they started punching the holes for 10/90 they added the punch to the tool and voila. In the interim period (maybe a few months?) they kept producing the tonneau base with the punch for the hole to accommodate top cover motor removed.
some more pics with details. If I got anything wrong I'll update them.

Oh yes I did
New OEM electric canvas top on order. None left in US. A few left in Germany. This is the original top not the replacement part.
Hesitated a long time on this, but definitely excited to get the top conversion done. Hoping to get this ready for this years Vintage.I BUY/SELL REFURBISHED CM5907s & CM5908s

You're the first person I've ever heard of to swap from manual to electric, it's usually the other way around! Just be careful when you're syncing the top motors and all of the limit switches. That's where the most critical sequencing comes from, and also where it usually goes wrong. When power tops fail it's usually because they came out of sync, and the motors worked against each other and bent/broke their linkages.

yup. believe me I've studied the problem at length for a long time. I have a very good fried Kyle with a restored electric top car that hooked me back in 2013.. one of the arms on his top mechanism popped last year, and his car was VERY well sorted.
Motors getting out of sync is indeed a severe issue. There's a test tool that's not too expensive which I may end up investing in. It's not just the motor sync though - when the top shocks wear it takes more effort to put the top up, which aggravates the problem. ditto with lube issues on the top itself.
I'll document the conversion with lots of pics for others.I BUY/SELL REFURBISHED CM5907s & CM5908s

Kudos on the electric top conversion. As you probably know, there's some difference in trunk carpet, so you might want to gather those as well. I recall swapping the right side carpet and the piece that hangs along the back the of the trunk when I converted mine to manual.
Sorry to clutter your thread, but are the frames different between electric tops and manual tops?
I've almost completely converted my electric top to manual; only thing left that I'm aware of, is to add the decklid shocks. I'm already using a manual top frame and canvas top. But the top is getting worn, plus it's aftermarket and I'd love to get a new oem canvas top. But I'm pondering whether I should get a new oem top for the manual top frame or for the electric top frame, seeing I still have the electric top frame in storage. I've heard the windows are different? And am I safe to assume, that if/when I reinstall the electric top frame along with a matching oem canvas top, it will work fine manually? Or does the frame need to be modified to work manually?sigpic

1) the passenger side rear mount on the electric top has some added brackets to accommodate the power top motor linkage
2) the electric canvas top has an extra bow at the front edge of the top. this is the '5th cross-arm' you hear about some times.
those are the only diffs I could find.

(un)fortunately I saw my friend Kyle's fully restored electric top in action a few years back and became fascinated with figuring out if a conversion was reasonable effort. I found out 2 things previously mentioned:
-- bmw offered an electric top conversion kit for convertible owners
-- my late model 07/90 manual top car already has all the sheet metal mods done.

If you have both top frames you can compare them in detail. I had never seen anyone post pics comparing the 2 comprehensively. About to remedy that in the next post :-)
Originally posted by robrez View PostI've heard the windows are different?
1) there were originally 3 top types, manual with sewn window, electric with sewn window (10/90-9/91) and electric with zip out window (10/91+). The window design has no impact on top operation.
The latter two have an additional metal bow near the front edge, but the bow is NOT attached to the frame. I'm not really sure what it's for other than to keep the top from sagging in front, and for the life of me I don't see why a canvas top with that extra bow wouldn't work just fine with a manual top frame.
2) There are 2 remaining part numbers floating around, one selling for about $2100 and the other for about $700. Depending on who you speak to the cheaper one superceded (replaced) the more expensive one. It's not clear what the difference in the tops are, and the same part numbers work for both manual and electric top cars.
3) I tried to find out more about the lower cost part number and was told it was NLA. The more expensive part only has 8 tops in stock in Germany as of this writing - none in the US. Yes I bought the pricey one. I want my zip out window and was afraid the lower cost part number had removed it (i have no idea and there are no pics online).

Comparing manual and electric tops, frames
I've looked over the years and never found pics comparing manual and electric tops. You sometimes see comments from folks that seem to know what they're talking about, but I never see any damn pic comparisons! that ends here.
CANVAS TOP COMPARISON
This is the interior view of my current manual top. It's a stock frame in basically perfect condition, very clean. Top is high quality aftermarket, replaced by PO, in great shape externally but showing it's age.
Here is my donor electric top, same view. It's the original OEM electric top from it's donor car, BMW logo and all, It a post 9/91 top off a 92 vert with a zip out window capability, but the window itself unfortunately did not come with it. FYI a brand new OEM zip-in window costs about $700 right now.
The first thing you notice when you compare the 2 pics (other than the missing window) is that there is an extra horizontal bow on the electric top. If you look closely you can see the ends of that extra bow are not attached to the top frame. So I suppose it's simply there to keep the canvas from bowing in the middle. That was probably needed for the top to store properly without manual intervention. I can't think of another reason why you'd need that.
Here's the OEM logo on the electric top (faded but you can still see it).
Here are exterior views of the same tops. Note the added stitching on the electric top
manual top

front edge manual top
front edge electric top
FRAME COMPARISON
Looking at the top frame, there's only a single difference I've been able to find and it's what you would expect. That passenger side rear mount has some modifications to it so that the top motor actuator rod can be attached.
Here's the manual version for reference
and here's the electric top version.
You can clearly see 2-3 additional brackets and some bracket mods. You can't see them very well, but nte also that the top shocks and their covers have the same part number across manual and electric. the pic seems to verify that's the case as they look the same.Last edited by bradnic; 09-03-2017, 05:51 PM.I BUY/SELL REFURBISHED CM5907s & CM5908s

^^ Thanks Brad! I will use my electric top frame for my new canvas top. That way I can sell my current manual frame and canvas top to recoup some money. I asked about the difference between the $700 and $2100 tops a while back on the Yahoo Group. It's too bad no one had experience with buying the cheaper oem canvas top. Who know whether the cheaper top is a lesser product without zip-in windows, but since it's NLA now, I guess it don't matter. Thanks again Brad and good luck with the installs.sigpic
