The passenger side axle clamp is made to straddle the junction of the diff housing and the axle tube. It needs to be there to have the bar in the correct position and clear the PS shock. Since the diff is not centered, the clamp is about 2 inches away from the diff housing on the driver side.
Installing the nut for the driver side link bar is a bit of a pain because of the tight clearance between the fuel tank and the frame rail.
Here's a post with some pics that may help:

The right side clamp goes right up against the differential housing casting on mine while the left side is about 2" from the housing.
The front mounts should line up with prepunched holes in the frame. The nut on the inside of the frame on the fuel tank side is a bit hard to reach.
