Max drum diameter on 1984 200S

[booblinker]

I put my rear drum off my 84 200s on the brake lathe at work, there is still a rust spot in the middle that is pretty deep, I'd like to get it smooth but don't wanna cut it to deep. I can't find the turn to spec anywhere.

Should be in the service manual, section on the brakes, it shows the minimum and maximum service sizes.
