Hey phil.. just make sure the 4 link bars are square with the axle and square from each other on both sides.. you might try getting a 4 or 5 foot 2x4 square tubing or angle iron and c clamp it to where the frame is true straight goin on back to where your 4 link is to give you another reference point... or a lazer level can work too if you can get your hands on one.. as for the pinion angle.. try your best to get it in the ball park range wuth a degree finder ( can get one from harbour frieght for like 6 bucks). Your 4 link bars have adjustable ends so you can fine tune it. Also make sure the rear axle is square.. and same distance on both sides measuring from the the front hubs on center.. i moved my axle back a 1/2 inch further just because it looked more centered in the wheel wells and help track better on the freeway
