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

The Chrysler wheels "should" fit fine on the dart, we didn't have any clearance issues. We've put several style chrysler/charger/magnum wheels on different cars because they're cheap, and look good IMO. But the Magnum wheels we always had to mill out the center to clear the hub. The inside diameter were too small. But on the 300C wheels that we got worked just fine, no clearance needed, but we did have to make some center caps but they were easy.
Got these wheels for $300 bones with brand new tread on them.


I really like those, and there is a set for $200 locally, but not sure how well they would fit as the 73+ darts have different disc, or something to that effect?
