Hey guys, I am looking to put steel wheels on my 70 challenger a66. I need to know what vehicles will interchange with my car. Any info would be great. Thanks,
Jim

Early A66 cars had " 15" rallye wheels & E60-15s " STANDARD, but since yours was very-late .....
Factory correct body-colored steel wheels with "dog dish" hub caps would've been:
14x6.0" w/F70-14 Goodyear Polyglas white streak or RWL
or
15x7.0" w/E60-15 Goodyear Polyglas GT RWL

'70 dated versions of either wheel can get expensive (there's a 14x6.0" set from a Charger listed here in "wheels/tires for sale").
Most of the big block mid-'70s b-bodies had 14x6.0" wheels.
15x7.0" wheels can be found on late-'70s Fury/Diplomats/etc. that had the bolt on wire wheel covers.

Thanks, thats what I was wondering. Wanted to go with that look, and didn't know what I could use. A buddy mentioned perhaps dodge truck., but the fury, diplomat shoul be just as easy to find. Would that be 74-78 or more specific in the year. For now as long as the wheelsook close I am ok with that. Thanks again
Jim

If you are good with the 15x7, I think MOST if not all the 5th Ave cars that didn't get aluminum wheels had them, new.
The fake wires, or deep full covers seem to be a good clue.
Of course there is the cop car ones ...

You can fit a 15x8. Use 4.5" bs. Wheel vintiques sells them. They look better on the back. Use 7" up front
