rear brake drum puzzlement

[stevair@webtv.net (steven wren)]

I'll agree with Joseph- don't remove the steel liner. It is probably
pressed into the alum drum and the pins are to keep it from spinning.
 I just had some alum drums turned(from a 80's G.M. car) and the max
they can go is 1/16 (.062) inch over the stock diameter. But,,, I don't
know what the stock diameter is for the roadster. I'm sure the shop
turning the drums will be able to tell you if they can clean up the
surface.
