Wow, that sucks man. I would replace the rod and get the sleeve pinched. www.rc-mushroom.com has the rods for $19. I just ordered 3 from them. I don't know exactly the size of the shim thats used but it should be just one silver shim. It's pretty thick so I think the .7mm would be about right. Someone else correct me if I'm wrong. Oh, and leave him negative feedback if you got it off ebay. Do you mind me asking how much you payed for it?
