sadly i sold my 79' z28 a while back and havn't been on this forum in a while. but i came across a tire inflator can that came out of my camaro, and i figured the best place to ask about it would be here! the GM part number is 9590399 was this specific to 77-81 camaros? if not what years was it specific to? specific to camaros only or generally any car in that time frame? i'd like to sell it, what is it worth? it's been collecting dust in the garage, don't want to toss it, i'd rather sell it and rehome it to someone doing a restore. thanks in advance!
