Re: 1804-5-7-8 Rear Brake Drums

QUESTION: The current drums I got last year that were on a car with perhaps 40k miles (could have been 140k. I had these drums turned and reinstalled.

Now they are scored, but the shop says they measured them and not only do they not have enough material to turn to remove the scoring, but they don't have enough material to put back on the car scored, which means they didn't have enough material to be legal after they were turned last year.

I'm wondering in the shop is going by modern specs and not old car specs. Those drums which take 2-1/4 wide lining are heavy duty. Where can I find the spec on worn drums for any of the following:
