Sifab offer 30mm stainless bobbins Rob. 54mm stainless U clamps
here.
ETA: no mention of the bobbins Craig used as being stainless!
Richard, my replacement Bobbins and U clamps are not stainless, I only used stainless spring washers. The new Bobbins are polyurethane and not rubber bushings either. I understand polyurethane generally last the life of whatever vehicle they are on ? while rubber Bobbins might need to be replaced multiple times depending on environmental factors and how many miles are accumulated.
I might consider changing the U bolts to stainless though, if I can get them in 54mm and 58mm ?
