Joe,
Thanks for the info. Truck is still in the shop (so I don't know how it will drive yet), but I went by yesterday for a pre-final assembly look. Considering all the variables above, I told them to add whatever leaves were necessary to get the front back to the "flat" configuration and base the rear off of that. They added back two of the three leaves in the front and it looks about perfect. In the rear, they removed the 2" lowering blocks the PO had installed, and removed the trailing arms (remnant of the 69 Camaro coil spring suspension; not sure why the PO left them) and the truck sits almost perfectly level front to rear without adding any leaves. Center bolt of the rear bumper is about 19-1/2" off the ground, and the center bolt of the front bumper is about 16-1/2". Now it looks like a real truck again. I'll pick it up tomorrow afternoon, my only concern is how it will handle/ride. The tech said the steering geometry should be fine...we'll see.
Thanks again,
Mike
