So I have since taken the drum off the passenger side rear as the brakes were binding heavily and found out that the wheel cylinder rear piston was seized solid. And stamped all over it was "Wagner Lockheed USA" and the drums are bang on 14" id.

Looked to me like someone had already had a go at sorting the brakes as the shoes looked new as were the cylinder seals and gaiters. Just looked like water ingress past the gaiters. So I cleaned them all up and plan to reinstall them.

Interestingly as well, I had assumed all the wheels were 17" RH5s but the fronts are actually one piece 16s. So that's half the wheel issue already solved! Happy days.

I think you may be right Stu that this might be on a changeover year maybe.
