Does anyone know where you could buy a diff shimming kit that includes the washers that go behind the two larger bevel gears inside the diff? The washers behind mine are warped. When you place them between two fingers, they pop back and forth. Whenever i put diff lube in the diff, it seeps past these washers and the o rings, getting all over the diff bearings. It seems to me that the washers are the cause of the problem as they don't sit flush with the diff case. I know that these shims are included when you buy the hpi alum. diff cups, but i dont really want to pay 30 bucks for 4 shims.

Any help would be appreciated. Thx
