74 -72 satellite front cap.

will the 71-72 front cap fit the 73-74 models.

No everything's totally different, including the body line on the bottoms of the front fenders. I'm sure the front fenders likely could be reworked however I have yet to ever see anyone actually try this conversion.

I think it depends on the body style. 2 dr cars are different. 4 dr and wagons were the similar with subtle changes.
