pinion angle question

[RexDodge]

I know this has been covered but I'll ask. In the photos below you will sort of see the pinion angle I have. I have installed a 2" lowering block and coils from an El Camino that should net me around a 5"+ drop. I flipped the trailing arm brackets to correct the pinion angle and now (without the bed or fuel tank in place) I have a slightly upward angle. I think it will work out but I'd like some experience opinions. I am thinking I'll wait until I get the bed on and a fuel tank (or simulated weight) and recheck the pinion angle. At that point I can either fab up some different brackets or install shims. So waddya all think?
