Reproduction wheels/caps

I think the stock wheels would have been 14x5 or 5.5. Someone here will know for sure. If you want 14s, you will have to hunt them, nobody in the aftermarket does 14s. Aftermarket 15s are available with 6,7, and 8" widths. Summit has a decent selection, just search the wheel section, specify 5 on 4" bolt circle. But you MUST check what they say the have in stock, or not available, or backorder.
There is another company besides wheel vintiques (summit), i think u.s wheel, or us mag, that also do 15" steelies for 5 on 4.
