I have a pair of new rear leaf springs for a 1968 Camaro. They are 2 leaf springs and each leaf is approx. .392 thick and 56 inches long. The tag says that it is: group no. 7.503; part no. 3935786. This information is from the "all purpose output card" that was sent with them from GM. I don't know what the code is or where the code is stamped, or if they were stamped. I ordered these springs from a Chevy dealer in 1969, but I don't remember what they are. I think they are off road springs, maybe for off road racing. I also have the matching coil springs for the front. The coil springs do not have any paper work with them. Both front and rear springs have never been installed. Does anyone have any further information on these springs. My Chevrolet Chassis and Parts Catalog does not list them.
Thanks, Larry
