1972 K20 rear leaf springs
Is this a factory spring setup? I haven't seen other helper spring packs like this and I can't find any mention of them on any replacement spring websites. I suspect this was added by PO. Does anybody else have this setup on 72 K20? Also, the main spring pack is 6 leaves, but all the replacements seem to say it should be 5 or 7 leaves. This truck has the 1G5010 heavy rear spring option on the spid. Thanks.
