X2 on the repair. I found a small stress crack on the b pillar at the corner :shock: Why would this happen? Body bushings worn out?

I think stress cracks are more common with t top cars since there is less strength in the body. I don't think more powerful engines help much either.

My 79' 2dr. Bu has cracks on both front pillars.

I suspect mine were caused because of a weakened frame on the rear do to some rust on the right rear frame horn and a lot of drag racing.

I hope when I get the better frame under it that I can take the window out and weld them up.

another problem rust

ok guys well after having some time to look at the car i noticed bad problem... ok years ago the car had been vandalized an someone cracked the windshield at this time the car wasnt mine, so the glass shop said that right there in the corner was rusted out pretty bad so they did a half *ss job of fiberglassing that corner where the cracks are... well if it was fixed the right way it could have been saved, however i now have to pull the glass out an hope that corner doesnt just crumble down, if i can try an weld in piece metal also looks like they didnt put the trim on right theres a gap in between the windshield an trim piece (underside) of it.. so i'll take some pics tomarrow but it's bad i'm almost at point of shiiit where to start to save this..

As far as I know they all do it, My mom had an 81 Camino the a-pillars developed small hair line cracks at the factory lead seams. They were repaired under warranty. They came back less than a year later. My 78 was like that when I bought her in 82. I have had the car repainted three time's in the last 30 years.they just keep coming back.
My buddy with a 87 Camino ground all the factory lead out and welded strips of metal back in place and metal finished them . the car was painted three weeks ago, and time will tell if our fix worked.

Guess i will keep that on mind when the "Bodywork" stage comes around... As far as i know my car hasn't been a victim of car thieves. I just hate the idea of them coming back. :shock: My car was involved in a minor accident a while back but it wasn't that messed up. i am looking into getting my paint job done sometime "soon" and NEED to find a solution that;s permanent. :wink:

That's pretty much what you have to do. My hardtop car had the stress cracks at the B-pillars originating right at the corner where the drip rails ends.

After grinding down my roof and melting out the lead you can see why this is a problem. I think its the only area where the factory didn't actually braze the two pieces of metal together. At the window channels they brazed/welded the roof skin to the side panel skins which is what I think helps keep things from cracking.
