18" Wheel help
It can be really difficult to find killer wheels for muscle car Mopars because of the bolt pattern, offset and bore size requirements. Ford did their fans a big favor by designing a bunch of custom rims that were perfect factory fits but Mopar never did that.
I had custom Fikse rims built for my car but they were super expensive. The wheels you're looking at are more of a BBS style road race rim. BBS rims are super expensive but there are a lot of cheaper knockoffs available. They are usually made for Fords though so the bore size might not fit and the correct offset might not be available.
Back when we were road racing A body cars we converted them to Mustang rims.
