5x4 Wheels

Heres a picture of the current ones on the front. The front are drums as well. I just want a bigger wheel that will fit the car in front. Im not sure what that dimension would be

Ok a bit clearer now.

Do you want steel stock type wheels or fancy wheels?

For stock steel wheels, there are 14" dia, 5x4" bolt pattern, 4.5" or 5.5" wide wheels that could be bought used OR new reproductions

So really your question should be what 14" or 15" tire and wheel combination will fit on the front of a 68 Barracuda without body modification.

Then put up a wanted ad for that wheel.
