Old Mopars are 5 on 4-1/2 aka 5 on 114.3 mm.

The new stuff is 5 on 115 mm, close enough to force on, but I wouldn't co it.
You're forcing the wheel stud to go sideways and it isn't designed for that load.

Wheel offset is another issue, late model stuff is a very positive offset (wheel center is pushed out in the barrel) so they're really deep on the backside.

Old 15x7's have a 4.25 backspacing so the center is slightly towards the front, but nothing close to what late model wheels are.

Late models also use a different hub bearing setup and don't have the protruding dust cap.
The dust cap on old cars usually sticks out to far to use the center caps using late model factory style wheels.
