Depending on how old. Most Mopars I have seen are 5 on 4-1/2 like the 49 and up Ford cars. I think there is a difference in wheel center holes though as it seems my buddies always had trouble with those back in the 60's when they were mixing and matching with get by rims and tires.
Hi The 50's big MoPars, like my 1955 Imperial are 5 x 5 1/2 as were the early Fords. I remeber in the 50's putting MoPar wheels on early Fords. I think I remember that there was a difference with the center that wouldn't allow the Ford wheels on the MoPars. I think the center hub centered the wheels on the MoPars.. Jan in Ojai, CA
