Post pinion angle

Well guys, I hope that you all can help me out. I am in the process of building my first hot rod and I have ran into a problem. My car came with a 10bolt and I traded for a 12 bolt. Icut the brackets off of the 10 bolt and cleaned them up. I also cut the brackets off of the 12bolt which was a coil spring car and slicked the rear end up. Then I bolted my 10bolt shock plates and rearend brackets back on the mono leaf springs, the I slid the 12 bolt into place. Okay every article that I have read says the to set the pinion angle the car has to be sitting on the ground. My car is jacked way up in the air because of all of the work that has been going on in underneath the car. Now what? Im ready to weld

I am not clear from your description whether you used leaf or coil springs in your finished suspension. If you used leaf springs, just bolt the unbolt down tight and wait to do the final pad welding until you can set the wheels on the ground and set the pinion angle. At that time, just loosen the U-bolts, rotate the housing 'til the angle is right, then weld and tighten the bolts.

My car has mono leaf springs, the car that I got the 12bolt out of was a coil spring car. The shock brackets and rearend brackets just bolt together and not with u bolts. The rearend setup has the rearend setting in the cradles of the brackets. If I put me some wheels on it and set the car on the ground the rearend will lift up out of the cradles. The rearend sets on top of the springs. Ive been told that I should use a -4 degree pinion angle. holler back
