thinking about doing this in the really near future. i have a 84 blazer with 6in suspension lift 3in body and will probably be running 38sor 39s, i have heard of two different set ups, one being under the spring, and the other over, which one would be better for my set up. also how bad will the engine cross member get in the way? is there a way that i can maybe bend the tie rod from the box to the knuckle to eliminate this problem. thanks for all your help.
