56\" rears- Reversable? I have some 4" lifted 56" rear springs, but their in storage. Before I start the lift on my blazer, I'm curious as to whether or not the spring eye bushings are the same size, so I can reverse the springs (shackle flip plus "block" welded to the axle will push the axle forward in the fender opening a few inches, while I want the wheelbase mildly longer) Also, the other question is how far out of center is the centering pin in my leafs. If it's more than 4" I'll forget about it and run them in the normal direction. Thanks for your help, Chad.
