Good luck getting the backlash set on that diff... I could never get mine right.

Had an epic day with the Verty30. First, I had to button up the rebuilt 3.73, then pull old Open diff then bolt in the 3.73.
Interesting find when I cleaned the old diff that I pulled off The Verty 30. There is a white “A” painted on top of the differential casing at he same location where the “S” is painted on the rebuilt 3.73 that I put in. I know everybody out there in BMW land swears that the “S” means that it is a LSD unit. I’m not so sure that’s true. Me thinks that “S” means it’s a standard or manual and the “A” means it’s from an Autotragic. The Verty30 is a five speed and the unit I pulled off was a replacement unit the original owner put in a while ago.
Also, I know the unit I pulled off is open but I’m trying to figure out its ratio. I indexed the input and output flanges and the input flange spins approximately 3.25 to 3.50 times for every out put rotation. However, based on the rpm output I’m thinking its a 3.73 open. More to come on that...Here’s some photos:

Wheels look great.

[flyboyx]

wheels look great. you found those really fast.

the "s" on the top of the diff means "sphere" which is auf deuche for limited slip.

Nice!

[Echo30V]

Yes, they came for sale locally and I jumped on them.

With respect to the “S,”. If that means Sphere then what does the white “A” stand for on the open differential I pulled off the Verty30 mean?

"absolute garbage" haha

Throw some smilies, euro bumpers and do a little drop and that vert will look so awesome, not that it doesn't look good already!

[Echo30V]

Agree MisterBurgundy, saving my sheckles.

Thank you Dennis, Verty30 running pretty good. Next up suspension refresh, exhaust and then not sure.

[MrBurgundy]

[Echo30V]

Yes, hard top. They are very elusive.
