AD body mounts changed? First I've heard of that. If I misread or that info is wrong, you should be able to swap out cabs between years on AD trucks. There is no mention of mounts changing in the JC page cited. The new aftermarket cabs are interchangeable so why not?
Doors through '50 had no vents and pull-down handles. 1951 doors had vents and pull-down handles. '52 and up doors had vents and push-button handles.
Everything else you mention should fit.
