They are different. 52 on back 3/4 tons had Huck brakes. They were completely different from later models. Is there a place in UK that can reline your shoes? sometimes thats the best way to go on some models. That is the correct size for the wheel cyls. I have a Napa catalog & that is what is listed but they don't show the shoes either. They do list the cyls & repair kits though.I believe Jim Carters parts store carries the shoes & parts for these. I put some on the rear of a 52 for someone recently & I believe thats where he got them.
