I know on my 450 there was an extra bolt on the tank that needed a round spacer, so I think I'll be a couple spacers short. Maybe I can find something at Home Depot to suffice. Started phase one today. Installed a brand new AC Racing 450 subframe. I ended up grinding down the bracket on the frame to fit the subframe. Figured I'd never go back, plus it'd be a lot stronger than shaving off the aluminum of the subframe.
