I'd find some way of accurately measuring them.  Some 10-24
all-thread, a coupler nut and two jam nuts and a couple of small
acorn nuts (for the ends, so the point radius is smaller than the
drum radius) might be a good start.

I had mine machined once and they came out all wobbly.  Shop said
that the way VW did the center hole doesn't work very well with
US-type brake lathes.  YMMV.
