Hit a machine shop auction a week or two ago, tucked away in a back room was a Chevron B-56 #82-03 FA car.
Tub seems intact as does the body work except the top engine cover appears to be missing. Front suspension is there but it looks like some of the rear bits are gone. Found brake rotors but no calipers. About 12 wheels of various widths. No engine or gear box. Last tech sticker date on the roll bar was 1990 or so.
The chap now running Chevron says there were 2 built, they were the last cars built before Chevron went bankrupt and was sold.
The auction website is http://www.tmadallas.com/, they had it listed as an "old Indy car body". Contact them for details.
