Rear wheel centering help

[muckyp]

My truck has had air bags for years and the rear wheels were centered equally. I recently put some lowering blocks on and now the passenger side rear wheel is considerably further forward in the wheel opening than the drivers side.
I installed a CCP double adjustable panhard bar and centered the axle left and right, but the passenger side wheel is still further forward.
Any suggestions on how to correct this? Shouldn’t they at least be equal on both sides?

I would look at the lowering blocks. The pin or hole may be slightly off center and one may be installed the wrong way.

Thanks for the suggestion. I did not consider that the blocks may be directional. Im not sure if that could change the location of the wheel location but I’m willing to check. I bought them from way2lo2, so if anyone knows off hand, chime in.
