I'm not planning on wasting any money on an aftermarket now that I know this. I didn't know about the donuts option / 'issue'.
Anyone know what size clamps these pieces take off hand? I think I have some 3" ID t-clamps sitting around in the garage, but if it's another size I'll need to pick-up/order-some. I definitely want to get away from stock screw-clamps as they're prone to failure regardless of the situation from prior history.
