Wanted urgently: S8 or URS4 rear caliper

[Colesy]

Just failed the MOT on a leaking (from around the piston) rear caliper.

So ideally I'm looking for a n/s or left hand aluminium rear caliper for an S8.

But an o/s right hand URS4 rear caliper will do the job too.

Happy to buy a pair if required.

The reason for the different sides is that the S8 caliper is run upside down when fitted to the rear of a coupe!

Have got a URS4 caliper on it's way to me, so will be looking for a place to have the S8 caliper reconditioned. Any suggestions?
