I'm going to order these springs for My 76 Camaro, and I was wondering if anyone else has ordered them.. My camaro is a small block with Aluminum heads, and Fiberglass cowl hood. They say you have to weigh the front end of your car before you order them, but it has no engine or tranny in it right now, and I want to get the suspension done before I drop the drive train in.. If anyone else has used them on a small block 2nd gen camaro, I'd like to know what part number you ordered.. Thanks.
