B5 S4 FL rear caliper fitment advice please


Old ones are the best ones
Hi again, recently acquired a b5 s4 facelift, managed to snap a nipple in the rear caliper, its the alloy lucas caliper with the vented disc, having a bit of trouble finding the right one, would prefer a used one if possible, is there any other model of audi/vw that i can take one from? many thanks.
