If you are talking about the ones that look very similar to the Magnum 500 style I used some for years on my '76 with front discs. No issues. Mine came off a 72-74 Charger - can't remember the exact year. Looked just like Ford rally's but had black center caps that stuck out more than the Ford ones.*
My Magnums actually came off a Mopar of some kind. They are 14 x 7's and I did have to grind a little off the top of the disc brake to get them to fit. It was only a small amount that really looked like a casting flash sticking up to me. I've had them on for 2 years now with no problems. The only way I even knew they were'nt Ford Magnums was a comment from a Mopar guy that the centers were Mopar and when I repainted the wheels, I saw that he was right! Hope this helps! Scott
I bought my Comet Stabber slots from a guy who had them on a 50's something Dodge panel van. I once had 4 lug chrome reverse wheel from a Chevy II on my Falcon...the center hole was larger than a Ford rim but the bolt pattern was the same.
The 15X8 Mopar police car wheels fit Fords. 14's should as well as long as they're disc brake wheels.
FYI, in case you don't know, Wheel Vintiques makes these in other sizes, in case you want bigger wheels for the rear.
