I know this thread has been dead for awhile, but I'm in the process of doing the shackle flip and had a question. What I have is a 71 K20. I bought the B52 kit and the Shackle Flipn-n-Switch from DIY4X. I was talking on the phone with one of their guys and he recommended using 52in rear leafs out of a early 80's K5 Blazer for my front springs, but we didn't discuss what springs to use for the rear leafs. I want to use a 56in spring for the rear. What trucks did the 56in spring come in? There is a local spring company that makes factory spec springs for all the old Chevy trucks, blazers, suburbans, etc. Basically I'm just wondering what truck the 56in springs came in.
