Not many aftermarket wheels for the Mopar 4''x5 bolt pattern.But they are out there with some searching.
Do you have the 4'' or the 4 1/2''bolt pattern ? Sounds like they may be 4''.
If so Summit has a 15x7'' Chrome small bolt Mopar rallye wheel without the center. #COK-MRYS-157
Price is $194 Not bad for a new chrome wheel.Summit has several listings but some of them are out of stock.
Don't get fooled that the 100mmx5 wheel from newer cars work. They are close but not a true fit.
A 5x4'' is 101.6mm. 205-225 is a good fit either in 14'' or 15''
