FITS Type 16P calipers on 2000 and all 3500 front calipers.
Hole in casing is 11mm
Also fits type 16PB IMPERIAL calipers with 11mm hole in casing

AS MANY CARS HAVE HAD CALIPERS SWAPPED OVER THE YEARS, YOU WILL NEED TO CHECK CLOSELY WHICH BOLTS ARE FITTED.

PLEASE NOTE THE THREAD IS 7/16 UNF IN BOTH PARTS, IT IS ONLY THE STRAIGHT SHANK OF THE SPECIAL BOLT WHICH IS DIFFFERENT  BECAUSE OF THE HOLE SIZE IN THE CALIPER BODY
