I'm planning to move my Dana 60 1" forward on my K5 blazer to help clear the fenders, and improve approach angle. I have 5-6" susp. lift from stock + 3" body (which I am removing). 38.5" tires. I'm running crossover steering, so the fore/aft movement wont be much affected by the move of the axle compared to stock steering. I plan to use 3/4" or 1" tapered blocks (there is already a 6* shim in there compensating for a very long shackle), and they will bolt into the spring pack. Probably use mild steel, and machine them on a vertical mill. Any thoughts? Basically, I need to know If I should: a) Redrill the leaf pack, have 2 center pins in it, drill the U-bolt plate for the old center pin. I have heard this puts more wear on the leaf pack with the extra hole. b)create 1" offset taper blocks, at a 6* angle. I have a Vertical milling machine, not hard to do. My DS seems to have about 2" more slip left where the axle is presently, so hopfully I wont have to re-tube or get a new 1Ton DS. Thanks for any input.
