Ok, so i called skyjacker again to ask about this. They say that 1969-72 used 52 or 56 on k10s, but, 1967-68 used a different length unknown to the guy i was talking to. He said they did not make a spring for those two years because with thier age and limited year range it wouldnt be profitable for them. But 56s did according to them come on some 69-72s, he says it is more or less still like a big 10 or heavy half (towing package) kind of deal, it wasnt to get around emissions like those, but still used the larger springs. Can anyone tell me what length spring was used on the rear in 67-68? Im just curious.
