Assuming you are talking about a 67-69 Barracuda, still with 5 on 4 bolt pattern.
Pickings are pretty slim for 5 on 4, and not cheap. Basically Cragars, slots if you can find em, steelies for hubcaps, and rallyes.
Depending on your budget, there are 15x7s (and larger sizes) from Team III/ET wheels that look like torque thrusts, (beautiful, but LOTS of $$$) and 17x7s from Boyd Coddington, also tt lookalikes.
American Racing makes a centerline lookalike that Summit lists, but i dont know if they really are available.
If your car has been converted to 5 on 4 1/2, all this info is useless, we'd need more info about your car.
