Can anyone tell me what steel wheels will fit on my 68 dart with the GM disc brake set up? large bolt pattern. Do Mopar 15x7 fit? Scott

Instead of paying through the nose for kelsey hayes parts, I bought an aftermarket set up that is comprised of GM parts, single piston, readily available etc. Problem is the mopar 14" wheels don't fit, so I am looking for 15's

It doesn't matter which caliper you are using (although some might interfere with 14" rims); the rotor and bolt circle (BC) used on it will determine which rim. Early rotor with a 4" bolt circle may be hard to find a 15" rim; late model mopar rim with 4-1/2" BC will be easier; if you figured out how to mount a GM rotor, then I believe they run a 4-3/4" BC. Guy up between York and Baltimore made some custom rims for us (The Wheeler Dealer).

If the GM kit had the Mopar bolt pattern, that helps. One problem... What about the hub center? It is supposed to provide the foundation to properly center the rim on the rotor. The lug nuts are meant to clamp the wheel in place, not to center the wheel. Anyways... The 15x7 rim from the Diplomat/Gran Fury cop cars will fit if your bolt pattern is 5x4.5. 2wd 1/2 ton trucks have this same pattern too. Later model Jeeps had 15x7 rims you might consider.
