Frame help ??

[hotsam]

Hey guys I need some quick help from you all !! My 72 k10 has some rough spots in the rear frame. Ive found a very solid 68 2wd leaf rear frame here locally. I think ive read the rear hangers are different but I already have a set of those ready in the box. This frame appears to maybe have the humps or "turn-out" areas where the rear coils would have been on a coil rear truck. But this truck was definately factory rear leaf 6 lug. So my question could I use the rear frame cuts to repair my k10 if I swap in my k series leaf spring hangers ? Thanks I want to get this deal done if I can use this. I cant get to the frame to measure as it is a far piece away in miles. Thanks again
