Hi new to the forum as of today,I have a 1983 Grand Prix that I have owned for 20 years and am trying to rebuild. I was 15 when I got it and did alot of dumb stuff like stuff it in a barn since 1994 and lost many parts. I am in need of a donor car for many parts,the body and interior are in good shape no rust,what I need is a engine,trans,driveshaft,rear end and the entire heater box on the outside of the firewall. have been looking online for donors and coming up with nothing. Any advice would be great thanks
