Escort Calipers?
 

Hi, I have seen some calipers on ebay that are new replacements they are for vented discs and are labeled as being for a "FORD ESCORT XR3I,MK3 / MK4, ORION, ESCORT LCV". I have read that these fit the Sierra and the guy said that they do fit some when I messaged him.
They have 54mm pistons apparently and are for 24mm discs. Have 4 calipers I was going to clean up but the pistons have chunks missing from rot!

Does anybody have any ideas they are a pretty good price.
Thanks Chris
