I’m looking for Urethane inner and outer spring plate bushing for my Oval’s. They are the type with out knobby bits on them. The rubber ones fit onto a 48mm shaft. Can you get them? Or are the knobby ones the same size just with extra bits case on. And if so can they just be machines off. Any help would be good.

There available from Vintage in Sydney 02-9789-1777, make sure you use plenty of Moly when fitting them
