Drums are NOS Ford.

Thanks to V8 Bob I now have the shoes turned around right! Embarrassing. You know I consulted two ford shop manuals, two ford IPBs, and two Chilton manuals and none of them illustrate a loaded Bendix backing plate with short shoes. I finally found dimensional data in a pocket size service spec booklet for 1950.

Anyway, i tweaked one pivot pin and did some light arcing at top and bottom of shoes. I am satisfied I now have even clearance through the full drum rotation. I think a combination of too close tolerances and heat build up from use may have been causing dragging while in use.

Anyway, tomorrow I will test drive and adjust prop valve as needed (as if it were a new install since I apparently had the shoes backwardsfor 12 months).

Will report back results.
