Ok so a bit more info, for interior bits it will need carpet, headliner (owner has rails) seat covers front and rear, 1 a pillar cover and I think the sail panels, owner has all the trim, door panels etc.
The car was originally bought in the midwest by his dad and was undercoated from the factory, he said about 50% of the original undercoat is there and the areas it was coming off were covered by him using a gm underbody product, says no rust was present. There was a small patch on the driver side rocker when the car was repainted, 4" long, rock dent/surface rust but that is it.
One thing I was not aware of is it has a fuel cell, original tank was taken out and was lost over the years. It sounds like the car was taken apart for paint back in the 80s and never fully put back together, the plan was to switch to bucket seats but that never happened.
The car originally was bought by the current owners dad, it went to the current owners brother in the 80s and he was more concerned with the mechanical aspect of the car and didnt care much about the cosmetics, the current owner bought it off the brother about a year ago but has a pro touring trans am he is building and would rather put the money and time into that, had a long call with the guy and he seems very trustworthy. It seems like the number is $30k
Carb is edlebrock, has the original exhaust and intake manifolds, distributor, and some other bits, no original carb. Motor was rebuild roughly in 2012, springs and roller rockers done with the cam, 1500ish miles since rebuild, no leaks.
Here are some trunk photos.
