Coilover injury

[cwspellowe]

I'd been noticing some weird handling and noises coming from my OSF coilover so jacked the car up to investigate, found that the tapered spacer between the spring and the top perch of the strut (tapered as in it locates the spring centrally, not a perch as such but the bush between that and the spring) had been smashed to bits and was chewing itself to pieces, allowing the spring to become dislocated.

Anyone know where these can be bought? Found plenty of places selling springs and a few selling the collars, but can't find these bush things anywhere.

FYI the springs are 60mm ID.

Oh also finally found a UK D2 service dealer. £180 per strut for any they have in stock, or more for the type "I" that the 306 comes with as they don't stock them. FML.
