I'm looking to buy a muscle car shell. I'm not too picky, my only criteria are it has to be 1974 or earlier and it has to be a GM. I'll take a Chevy, Buick, Pontiac or Olds. I don't particularly care. Preferrably WITHOUT an engine. I don't want to spend more than $2000 on it (two grand is still pretty steep for a shell with no engine)
If you have something like that, please let me know.
