My axle was real far forward in the wheel well before I did anything. plus the rear end was squatting with the blocks that I used with my 4" lift. Never planned to keep the blocks, but thought I was going to get spring during the swap but opted for the shackle flip. So between the shackle flip and the zero rate, I have a level stance and the axle is not so far forward in the wheel well.
Also, when I did my swap I was worried about the pinion angle because I was using the corp14 perches. So I feel like I got lucky on the angle. Get your springs or shackles and every thing before welding the perches and you will be able to dial in perfect pinion angle.
