I hear you about cutting ***** up. I don't have much choice, so I have to lop the top of my front diff off just to make the steering work correctly. One thing leads to another as we all know . . . the joy of mixing two lift kits and working around our poxy rules.
Have you looked at
Off Road Design's shackle flip kit and greasable bushings. Nice stuff, works way better than factory, and you get to throw those ugly ass blocks in the bin. I installed the u-bolt reversal kit as well. The factory retainers were pretty corroded as they hold water and mud which you can't see unless you get right under your truck. Mine wouldn't have lasted very long at all as the factory u-bolt had all but corroded away
