Using LX (New Charger/Magnum/300) Wheels on a 74 Dart

No sorry but I will have to call bs on the 2 different sizes. there is no way possible that the wheels would have 2 different bolt patterns that would be an extreme waste of cash having 2 different sets. the base model steel wheels are a 5x115. so why change for other wheels. they work they bolt up but I won't trust them on my car.

5 x 115 is what the Magnum, Charger, Challenger, and 300(c) have.
These are all the RWD and some AWD platforms

115 / 25.4 = 4.53
Effectively the new Mopars are 5 x 4.53 instead of 5 x 4.50

The 300 that is FWD like the Intrepid, etc is 5 x 114.3
