here's the problem, the brackets fit perfect! I would have to cobble things up if I were to move the brackets to the correct angle. thinking the bevel washer idea may be my only out.
first pic is of the brackets from the left rear:

next pic is from the underneath, looking to the right hand side:
oh yeah, and I have a gripe too. if anyone buys the off the shelf Taiwanese bumper brackets, be SURE you look at the face of the brcket that meets the bumper. if it's not straight, get an agle grinder and make it straight. or..... you will install the bumper and find out that the irregular face of the bracket has caused a visible dimple in your NEW CHROME BUMPER!!!! bit p*ssed about that too......
