67-69 Dart 4.5 bolt pattern wheel question

I am switching a 1969 Dart over to 4.5 wheel bolt pattern. I want to put 15" Rocket Racing fuel wheels on it and looking at 15x7 with 4.25 backspacing for the front and 15x8 with 4.5 backspace for the rear. Will these work ok? Thanks for any input.

I am using 73-76 A body disc on the front and changing the rear to 10x2.5 backing plates and shoes.
