I don't know why not. the front fenders are the same from 70 to 81. I would think the the core support would be the same. but you may have to do minor work to it. hood hinges may be the same but I would use the hinges for the newer hood if you have them.
My uncle put a 70 front end on his 74. Looked pretty good.
