Richard Petty 65 Barracuda? (Probably a replica)
The owner of the 2nd car would tell us in the 80's(?) that he owned this car and we didn't,well, at least I took it with a grain of salt. Said he got an extra blue rear plexiglass window for the King himself....after he verified the car was his at one point. The now owner sold his stash of NOS goodies and his brother helped him with the restoration. The car was then on display with Petty for awhile before coming back to Illinois. It's history has been in magazines so you don't hafta take my word for it.
