    I need the torque specs for the spring pins and U-bolts. Any other ones you have through them in too. Thanks Wayne.

    The best 1/2 impact you can find, 120 PSI, and as tight as they will go. :)

    Pins 45ftlb is more than enough once you clamp the leafs together with a couple c-clamps. Factory speck on the U-bolts is 150lb according to chiltons but there is a problem with aftermarket springs on the front. The front stock springs are wider than most aftermarket. I managed to bend a top plate at 150. try 120. Also need to have the weight of the vehicle on the springs for the final torq. Go back and retorq after a couple of hundered miles.
