Purchased this a decade ago and just never found the time I hoped to put into it. Rear-end was hit when I purchased it. A shade tree mechanic pounded it out and got the trunk lid sitting pretty square. The rear quarters and trunk had some holes that needed to be filled. A fiber-glass patch covers over a rusted area directly over the gas tank. The floor boards are also rusted on passenger and driver side. Quarter panel windows didn't work and I haven't the geometric skills to reinstall. (bought parts, but I think there are still some replacement rollers missing. Currently plex-glas, fills the window spaces.) Engine seems healthy (starts easily and runs smoothly) . The engine has been replaced with a 1968, 383 4barrel, with 727 trans, 8-3/4 differential. Brakes are there but soft. I replaced the master cylinder and brake cylinders at all four corners, bench bled the MC and the brakes, but still seem soft. (booster issue?). If Grade 4 is going for $8,000 (based on Hagertys) this feels like $4,000 might be reasonable, given the solidity of the outer body and rarity of these on the street.
