Sanding the lining is not a problem I had to do the linings on my '46 Coupe, as there was no place the get the shoes arced. There are several ways that I read in the posts on how to do it. I decided to make a "tool" out of a piece of maple, that would be easy to use, and give an even profile across the face of the lining. The arc of the "tool" closely matches the drums, I used a 5" stick on sanding disc, and it works well.
