No, have not replaced the clamp. Will aim to strip down the whole assembly in the next couple of days. May have to bite the bullet and buy 2 overall kits. Aust post is making a fortunate out of me with all these orders

Pin side has some good write ups for the bounce, saw member dluth comment on one with success. Going to add washers to the cup, and firstly try bending the backing plate, the ball is just banging into it. I'm guessing I replaced it in as lightly more forward position,despite using the same screw holes,in any case it did work well before I added the cliffy. But I reckon I will end up removing and adding foam. Will let you know my results.
