Common wheels to tow a ‘64 Barracuda

i'd scare up some 5x4 to 5x4.5 wheel adapters and then hit the yard and get a pair of spares off like a jeep or something.

5x4.5 opens up A LOT more wheel and tire size options and if you don't want/need the adapters and spares after the trip you could probably sell them for like 1/2 of what you paid.
