Red 1968 Barracuda Coupe Basket Case

thanks, yeah i noticed that, did they use old stock early on in the 68 model year? its a 68, 318, 3 on the tree car according to the sn

No sir. When the car got the little round side markers ( 68 0nly ) the rear wire harness changed a lot. You will likely find the reverse lamp sockets and wires inside the trunk.
