    Found a donor vehicle today, a 75 K20 suburban that I was hoping I could use the rear leaf springs with a ORD shackle flip for my 70 K5. Are these factory springs 56"? Can anyone shed some light on whether or not these will work? It also has the tranny and transfer case which I didn't check but I'm assuming it would be a th350/203. I will have to take a look on Monday.
    Thanks!

    75 K20 will have 52" rear springs.

    Tranny/tcase, if its auto, then you are correct th350/203, if its a manual, then 465/205

    I'm thinking I may just buy new 56" springs with 2 inches of lift. A stock spring with the ORD shackle flip IIRC gives you about 3 inches right? I'm looking to get about 5 to 6 inches overall. I guess I could get stock springs and add a leafs. I'm going back to junkyard this weekend.
