Things are coming along...my dreams of this car are shaping into a reality :)


I got my welder back which allowed me to fix my daily. My radiator support has been hanging because it broke on one side. I set up the welder and practiced. This is my first time TIG'ing and my first time welding aluminum. Really fun and definitely takes skill and lots of prep. These were my first "first beads"


After this I decided I can tackle the repair on the radiator support because it doesn't have to be pretty. Just strong enuf to hold it together haha. So decided to try to weld on my back lol.



Just tacked it in position then took it off and "finish welded" it lol.

It wasn't picture worthy so I buttoned her back up.


Installed a Tow hook as well because I plan to track it soon and heard they'll pull you by the a-pillars if there is no hook. Not sure if I'm gonna keep red or paint black.



The fender finally got primed and put back on...I'm kinda done with body for a while. Gonna focus on buttoning up suspension and getting the motor in.



So this Wilwood kit was in order from Ireland so I can put my wheels back on :)



I lucked out bigTime and had the perfect sized sockets. These are the only two I have this big and they are perfect for the each bearing. What are the chances.

So the first race goes in with TJ (Thor Jr.)


Success :). That was scary!




Flipped it over and did the other side, then stuck a bunch of grease in there, packed the bearing and followed it with the seal.

So how hard was getting that bottle in and out of the passenger seat?

Not too bad. It only weighs about 50 lbs. tops.

The engine bay came out really nice.

I'm shocked of how practical and spacious that trunk is.

Thanks! A corvette is honestly a very practical daily. Better MPG than my e30 if I drive chill. AC, heated seats, removable top.

Great work so far man. Sucks the welder took a shit. I had to warranty my welder to but after that its worked perfectly.

So, everyone who expects cheap paint jobs needs to actually do some body work. Body work is a nightmare and takes forever so I've been putting it off. But finally got all the paint off and primed it. Weather has been nice so probably will work on it more.


This was after 3 coats of Jasco and flapping off the loose stuff with a 80 grit flap wheel

Then started wire wheeling the nooks and crannys


This is where I was sick of using the drill and decided it can be primed. So I wiped it down with denatured alcohol.


Finally bought a 80CF argon cylinder for the TIG, also a Miller Digital Elite hood, TIG gloves, and a cart.



Was so stoked. Got everything set up and put the welder on the cart and wheeled it out to the garage. Plugged it in, turned it on, and NOTHING! My machine won't turn on. Really bummed because I wanted to weld that day. Also wanted to fill the holes in the engine bay I'm not using.


So I dropped the welder off at the Miller warranty shop to get fixed and waiting for that to return. So I primed they bay so it won't rust.







Took off the fender to strip it some more and get it primed. Will probably finish that today after work.

I would tackle any surface rust with a wire wheel on a drill. You can get them from harbor freight and they're super cheap, plus they'll last you forever. Then just hit with some primer to make sure it doesn't rust again.

I did get the wire wheels, they didn't work as good as the flap wheel with 80 grit for removing rust. But what worked best for the paint was Jasco! :)


I haven't decided if I wanna sand the rest off or hit another coat of Jasco.

Now that I got my daily back in order, I worked on the 02 some more because I got the parts I needed from IE,

Strut insert spacer for the bottom of the strut.

Pop these bad boys in...



Then slip your shock in, springs, and camber plates and you have your coilovers! I need to get gland nuts for the struts.

I like em :)

Then I decided to tackle some of the surface rust from the brake fluid all over the firewall/passenger side frame rail/inner fender. What's the best method for this? I was using a 3" flap disc for a drill. It took me an hour or so to "shave" all the tabs and grind a majority of the surface rust. Is this just always a lot Of work haha?




Pulled tabs for wire harness and ground off surface rust spots.



Drivers side

Passenger side


Got some good surface rust all over
My pedal box and booster assembly as well.

Also started re assembling the front suspension.



Pressed out the new rubber bushings in the arms because I will be using Ireland Engineering polyurethane.

Put primer on these control arm rod things too. What are these called lol?



Here's a new arm vs old arm. Old arms had poly bushings that are actually still good.



Both arms



After those were done decided to clean up and "refinish" the hardware.



Wire wheels are awesome. Grimy to clean
Then gave them all paint.



While that was drying I decided to start removing the chassis wiring harness. Got it all disconnected and confined to the corner. Then decided the booster had to come out too.



I managed to pull it off in one piece. First I removed the bolts of the pedal box. Found some rust...





I've got some cleaning to do in here as well. Sound deadening was not removed well. And some rust repair :(

But it came off with some Finagling. Gotta clean this thing back up and make sure it's working. Will get e21 MC for a cleaner install. (Single vs dual line)

Now the bay is ready to be shaved and worked on.



This is where I left off.

Got some progress done. My dad gave me a Dewalt chop saw so I went and got a metal blade quick :) started measuring to convert the struts to coilovers.



Make one cut 3" from The top of the strut.

Then you're here



Then I measured 12.75" from the bottom of the strut.



Which gets me to here



Here's my ghetto rigged set up.
But it worked haha :)



Repeat for the second strut. Then you'll be ready to weld!



Tacked up the provided perch from Ireland Engineering sleeve kit.



Laid the first bead



Then finished it all around top and bottom.



Was cool, there was smoke in the bottom of the strut hat wouldn't come out. Guessing cause of the heat?



Here are the struts done. Pretty pleased with the outcome. Surprising myself.



Cleaned and primed them.



Then got them some paint



And slid on the adjustable collars...



I just need the spacers for the strut inserts then I can finish assembling the coilovers.

But here's a sneak peak when I test fitted before paint.



Will finish once spacers arrive.

awesome work! I had an early 2002 project. I got as far as disassembling an extra m10, then I sold it all. I don't regret it, though, the front cowl was demolished by rust, but the struts were clean.

I'm lucky, no rust here yet that a wire wheel doesn't blast off in a sec. It's just some surface rust here and there. Gotta love California cars. The worst area is the rocker panel and the pedal box. Might have to do a little more than wire wheel it there.
