I'm getting my B52's setup, I marked the frame with a cut off wheel on both sides where the factory spring eye hole is located. You can see the mark in the pic with the tape measurement. I first match drilled and mounted the pass side b52, I went off how well the rivet holes lined up. I know the rear hole is suposed to be aprox the same as the factory hole, but mine is about 1/4 to centerline of bolt different, no big deal. Kert said just go off the rivet holes. So, now in doing the driver side, if I match the 1/4 measurement like the pass side the rivet holes are not even close and the distance from spring eye to eye is off, as you can see it measures about 1/8 to center of the bolt. But if I line up the spring eye to eye measurments from driver and pass side the mark on the frame is off, but the rivet holes line up better somewhat.
I would think logically the spring eye to eye should be more impostant then the mark on the frame, Do you agree? The pass side is done, I have to not locate the driver as good as possible so the truck drives straight. I'm measuring the eye to eye by putting a 9/16 bolt in the B52 hole and measuring back to the back edge of the bushing. These bushings are temporary just for measuring.
