Quoted from CoolCatPinball:Ok, easiest way to bend the upper bracket is this. Remove the Axle sculpt by removing the 2 nylock nuts. Once that's off, there's a screw holding the end of the bracket in place. You can gain a little bit of clearance by adjusting the bracket there. I had to gain a bit extra with some pliers. Once that sculpt is removed, its so much easier to maneuver and see what you're doing without damaging anything.
Thanks for this info !
