Replacing original radio and dash speaker in 68 Barracuda
67 has to have inst bezel removed as it has 2 "posts" for knobs. 68 has thumbwheel, so you should be good without removing bezel.
PS, the single speaker up front...there is a member on here that sells an adapter/bracket, so you can install 2 small round speakers instead of the single 4x10.
Good luck
