Opinions on this '68 Barracuda

Welcome. Have you seen the car in person? Started and hit the road? I think if you are still thinking about it. As suggested, see if a FABO member with knowledge lives near by. Or get an inspection. If you don't mind the mix match parts, and it runs stops and is as advertised. Well it is only money.
I have put $2500. Into a $4000 Swinger in 3 months. Due to injury I dont do my oen work though.
I do however do my own stunts. Good luck and hope you find your ride.
