Wanted: '65-'66 Brake Caliper (passenger side)

[OldGuy]

Guys, I'm in need of one passenger side brake caliper core (or at least the bare casting halves) in rebuildable condition. The unit I'm looking for accepts the 3/8-24 threaded brake hose. I have a '67-type (that accepts the 7/16-20 brake hose) to trade if someone needs that particular type or will purchase outright.

Thanks in advance for your help.
