edelbrock shocks

i have a set thats for a mid 80's g-body, these are performer IAS shocks , almost 400 for the set, im sure they would fit my 96 roadie, and look very heavy duty, does anybody know anything about these shocks, they are part numbers 3377 & 3477, calls for 3379 &3479 , cant be much of a difference, and would be putting in the cc623s

The Mid 80s G body use the same bilstein rear shock as the B-body but a different front (0949). The rear, at least, should be fine.

thanks, ill try them, might be better than having air shocks in the back ???
