Pinion angle question

So I need to mock up my ubolts bolt everything together and lower it down check it again. Ok thanks I'm gonna have to get my tires on my rims then lol
Another question my leaf springs move side to side about a 1/2 inch or so is it ok to push them over as far to the center as I can to help with tire clearance or will that cause wear on the bushings and springs?

If your springs are in the stock locations, the perches need to be 43" center to center. If you push them in narrower, you'll put a bind on the springs. If you want them in further, now would be the time to install a 1/2" offset kit and weld the perches in at 42" c-c.
