I'm replacing the brakes all the way around on my '69 F-250. I had three of the drums machined and one was too badly scored. I got a new one from Rock Auto for around $26.
Two questions:
1. Can I just use the one new one, or do I need to replace both sides at the same time?
2. Do I need to have the new drum machined to true it up?

re: Drums
The individual brakes don't know a new drum from an old one as long as the drums are within max dia tolerance and the shoes can be adjusted properly.
I would always do a light turn on a new drum just to make sure it's true. Nothing worse than going to all the trouble of putting a new drum on if its out of round a bit.

re: Drums
You can use just the one but replacing both at the same time is recomended. Makes them easier to adjust.
Are you talking front, or rear axle?
In a pinch you can get away with replacing only one drum on a rear axle but for that price Id do both if its the front axle.
Our drums are a 12" ID X 2" or 2 1/2" deep cast iron drum.
Thier cast, thier cut, and then thier put in a cardboard box and thrown around several times before you or me get em.
Some parts stores stock them on thier side on the shelves for months if not longer then drag em down and throw em on the counter for you to buy.
So Id always recomend turning them lightly after assembling them onto your hub/s.
They do get out of round and they do have to be turned after thier mounted to the hubs. After you beat hell outa one to get all the studs pressed all the way in Im sure you will agree.
Nothings worse than installing new drums, shoes, etc. and stomping on the brake pedal to feel it shuddering under your foot. Or in extreme cases where thier out of round, having the truck bounce to every stop.
Brakes are the one thing on anybodys truck that they should NEVER skimp on.
Like my Dad used to tell me. "Son, even if it dont run worth a damn youd better make sure it can stop"
