Looking for correct front and rear spiral shocks for my 70 z28. I realize it has been talked about here in the past, I want to confirm fitment of a expensive shock purchase and do it once. Now the rear spiral shock number is 3192282 and avalable from D&R classic. The front shocks part#3192132 are not avalable that i can find. Is there a source to buy the 3192132 front shock or do i have to use the 3192477 as a substitute sold from D&R classic,And will it fit the 70 camaro if i have to use it? Thanks Ron.
