On my 48' Plymouth the original steelies have clips to hold the caps and I can't seem to find any babymoons that fit them, they all seem too fit the wheels with nubs...anybody know where I can find them for clip on?
You might try Jim Carter Truck Parts in Independence, Missouri. Old Chevy/GMC trucks used wheels with clips. If unsure about whether it will work, check the return policy and order only one for test purposes. Good luck.
