Hi, thank for the info. I thought about the frame rail thing. The 37 Chev in it's natural state already has about a 4 inch channel in the back , and a 2 1/2 in channel in the front. Since I am using 2x3 by 3/16" thick frame rail I'm thinking the frame will only be seen at the very front of the cab.

The local hotrod shop said I should be doing my Z's at a 45 degree angle. Will the 90 degree angle you suggest be just as strong ?

If anyone has some pics of how a suicide axle with cross steer looks I would really appreciate seeing them. If I can suicide the axle then maybe I don't need to kick the frame up in the front much . 2 " maybe ?
