DB,

FWIW, check out this link to a MA law regarding maximum oversizing of vehicle brake drums.

MA Law on Brake drum turning limits

Provides very detailed rules to follow. Since your truck is before the 1971 manufacture date cut off, it is essential that you find the maximum size limit markings on the existing drum to make a final determination. Without that marking, I doubt any shop will even consider cutting your existing drums.

These drums are reproduced and available through most of our normal vendor sources.

Thinking easiest option is choose safety first IMHO.

Hope you find this info helpful. thumbs_up

EDIT: See you have posted while I was putting this reply together. Good on you for deciding to replace them!!!
