1978 Aspen Super Coupe, what's underneath them?

F body, that suspension have those rubber isolators. Gives it a somewhat soft ride. Those can be replaced with steel though. Now, the PS box is just mopar like been around all during the 70's. If it is a super coupe, no doubt originally came with an 8 1/4. The fender tag has code for super cope, "A" something.
Super coupes are desirable in the F world, but condition is everything.
