T-top rust damage


Here are some pictures of rust damage that was under the seals which in some places it has gone through the sheet metal. What would be the best way to fix it? Is this a job for a body shop?

It would be a rare body shop that would take that job at a price you would want to pay.

Re: T-top rust damage

WOW ive never seen a t top area ever rust out like that W.E.G and if that happenned to mine i think I would just look for a better shell. Its just too much to trace down as if it got in there then where else did the water go to rot it out

Re: T-top rust damage

I had the same problem on my 1991 rs, the t-top bar was gone, luckily I was able to clean up most of the rust and bought a oer t-top bar

Re: T-top rust damage

Thanks again! You guys did a great job. I took it to the car wash the other day and there's only 1 spot that drips but I think it's normal there. No more full shower inside the car.

Permanent solution right here. I had my car repaired with brand new replacement channels and couldn't be happier.
