You used incorrect part to bolt it on.
This small "aluminum looking" piece is just a spacer, meant to be placed on the leftmost 2 bolts in your pic.
You need a big steel (black) part with 3 holes, which goes above it.
I don't have a pic on hand.
ah. well, that's because I'm an idiot.
Damn. Ok. Now I need to find what you're talking about.
