Need help

[vht]

Has anybody got a ad truck with a tci or something similar front susp? I'd like a rough idea of how far the center crossmember is off the ground with a eng etc in the vehicle. I've got a frame with the frt susp installed. I'm setting up a 4 bar sys in the rear and with no weight on the vehicle it's hard to determine how it's going to set. If I was a little more familiar with these trucks it'd help. I'm planning on setting the frt end where it's suppose to be, setting the frame down 2 degree, and setting rear end up 1 degree, but I'd like the lower bar to be parallel with the ground. If anyone see's anything wrong with that, please speak up. 4 link kits in race cars tell you center to center on the shocks, loaded, frame height and everything else you need to know. This sw kit has nothing and the tci kit I had, had very little. With the 4 bar, the pinion angle shouldn't change as the rear end moves. I figure the coil overs won't compress much over a inch with no more wt on the rear these trucks have. I have a few adjustments, so if I get close I should be alright.
