Hi everyone,

I am in the process of restoring a 77 Firebird Formula. There is a lot of rust damage and I sort of have a plan for most of it, but I am wondering about the rust that is just below the rear window seal. Would I just cut the rust out, shape some steel, and then weld it on? Any suggestions would be appreciated.

Sometimes you can panel bond small pieces in and sometimes you need to cut big sections and weld so there's more than one possible answer. Pics would get you better recommendations.

For that much rust, I would buy the whole package shelf, rear bulkhead assembly. That panel, at least to me, looks like saving it would be a very difficult job.

 

If I were to attempt to do a quicker fix of the rusty area, I would want to find a nice rust free panel from a parts  car. Then cut off the rusted areas of the window. Then cut a rescue panel from the parts car panel.

 

The window filler panel is readily  available from restoration parts suppliers and is not expensive. The package shelf, rear bulkhead panel, last time I checked is not available new. So a used one would have to be found.

Okay great. Thank you for the feedback. The rear bulkhead assembly sounds like it would be better in the long run. I had not thought about that previously. I dont know a whole about the parts. When you say bulk head assembly are you talking about everything from the top of the window down to the quarter panels and rear?

That's it. I'm glad these have become available as rear window rust is a major problem.

For the rust that is on the quarter panel part of rear window area, I believe you can make your own patch panels. You didn't show if rust extended to roof panel. How does the window area there look?

 

The trouble with rear window rust is that it affects so many different pieces of sheet metal.

 

I'm including 2 pages from 67-76 parts book. Your newer car uses same sheet metal.

The top seal of the rear window looks good. Yeah Im sure the rust extends beyond the actual part(s) that I will get. Ive never shaped metal or anything like that before. Im not in a hurry though so I have plenty of time to play around with it.

Thank you for that parts list. It will help a lot.
