That's what I thought.
But Don has a late-model BJ8, which should take the 1/2" rotors, right?
Sounds like he might have calipers from an earlier car?
Moss, for one, shows one part number for all 6-cyl cars with disk brakes
up to #26704, another for later cars. I assume the later part# is the 1/2"
part.
