Has anyone put the 63" IFS (89-9?) rear springs in the rear of a 1st Gen Blazer? I have a line on a set and think I am going to try it. I already have a shackle flip in the rear so I should be able to move that back (and swap sides) to get the shackle mount taken care of...the front is what would be the hard part. The front hanger is on the area of the frame that slopes down and the body mount might be in the way? I have thought about buying another shackle flio bracket from ORD and bolting it in as the front hanger but I would like to use the stock hanger to save some $$$ (I need to buy shocks to replace my stiff rs5000's). What-ya-think?
