I would Absolutely NOT let them remove the drum. Especially for sake of replacing studs just because unless there is a bad stud. They can be turned in tact as all of the early ford drums.
I press new cast iron drums on Model A’s and turn them and flathead v8’s all the time and as hard as they are to come by would not even entertain it. I’m sure they do know brakes but modern brake places don’t always understand the complexities of the old parts. And the liability will be on you not them. Just ask them . I’m sure they will not accept replacing them if they crack them in swedging new studs. They’ll just say sorry we can’t get them.

For some new Lincoln parts try Boos Herrel . I use to service a bunch of v12’s for a guy and obtained many parts from them . Worth a call anyway. You will probably have to leave a msg and they will get back.
