Project Updates:
I hooked up the old exhaust system; I found exhaust reducers 3" to 2.5" then a 2.5" to 2". The old exhaust system uses glass packs, it’s still loud, but no long breaks windows with the engine running

. I will install the Edelbrock LS conversion exhaust system after completing the body restoration. I have not run the engine very long since I am unable to check the transmission fluid level. I'm still waiting for a Camaro trans dipstick. It was not stocked by any Atlanta area dealer and had to be special ordered.
In the mean while I have been doing body work. The quarter panels didn't drop in as cleanly as I hoped and will require a lot of work to make them look show quality. Work that pushes my fabrication skills to the limit and beyond. So in the mean time I have been doing rust repair to get ready for my nightmare quarter panel installation.
Here is a picture of the before,
Replacement of some of the missing metal.
The upper right rear window channel patch.
The upper left window channel cut out, there was not much left of this piece
Almost done with making the patch, final trimming and tweaking still to do.
And the tools to make the patch. It took about 20 minutes to get the patch cut and shaped as show above.
