My 1970 C/10 has Heavy duty front springs and heavy duty rear springs listed in the glove box. I also saw a 69 C/10 that only had heavy duty rear springs listed. I don't know what the difference is, but I heard somewhere that the heavy duty coils for the 1/2 ton were the same as the normal 3/4 ton ones. I really don't understand it though, but I don't think 1/2 and 3/4 coils are the same.
