    Lift will be 73-87 for trucks but 73-91 for blazers, suburbans and crew cabs.

    only problem you may run into is the difference in spring eye size for the rear eye on the front springs. I believe they were 7/16" in the pre 87s and the 87-91s were 9/16.

    You are correct, but that is easily fixed.

    would that be fixed by like drilling a 9/16 hole in the spring hangers? bc that wouldnt be that hard or would it comprimise the strenght?

    You would drill the shackles to 9/16" and use a 9/16" bolt instead of the 7/16" bolt.

    or you could just buy new bushings that are correct for your truck, they should fit right into the springs.

    I took the lift on my 87 off of a 76. Bolted up just fine. But little did I know, the springs and shocks were trash. Now I'm in the market for 4 new 4" lift springs, but can't afford brand new ones.
