Sounds like a good plan.
Even with a very close adjustment, these shoes seem to fit and perform well after some miles and wear. Years back as you may very well know, they would arc the brake shoes using a special brake shoe grinding tool, instant great fit.
To be honest I did not use the Ammco or Miller tools, but followed advice from Dodgeb4ya, and set the brakes arrows on major adjusters pointing as per shop manual, drove for x amount of miles, adjusted minor adjusters periodically, and brakes were great.
I sold this vehicle to a vintage Mopar collector last spring, he told me they are the best brakes he has ever had in a vintage Mopar. You could put your passenger into the windshield on a hard stop.
Dodgeb4ya Bob, is probably the most knowledgeable and experienced Guy on this forum with these lockheed brake systems, He could adjust them in his sleep no doubt....good luck ps spec on the brake drum is 10.060, 60 thousandths over, drums can be machined oversize to .030, thus giving .060 max oversize.
