I just finished installin some in my blazer this past week. Knocked out all but 1 rivit on each side, rotated the hangers forward, use the ORD flip and moved the it back to where the front holes went into the original rear holes on the frame (had to cut off a portion under the flip, no biggie tho) and used 6" shackles. This gave me a perfect shackle angle and with a 1" zero rate with 1.5 offset it moved the axle back about 3" which is what i was looking for going into this. I had 7" of lift when i started and ended up with about 4" in the end. Used a 4" shackle flip, 6" shackle (like mentioned before), 2 leaf 63s with overload and added the 2 and 3 leaf from my 52s to that spring pack to stiffen it up some and to add height to the pack. drove it finally today for a bit and it is really soft. it can be a lot of work to get right and might be worth it in the end. I know it is/will be for me.
