Great pics!
Porterfield will arc their linings. I gave 'em the diameter my drums. The drums I had lightly cut at East Coast Machine.
Another lining place that will arc them is Rochester Brake and Clutch. Locally, I think you just got to sniff around. A local parts store (now closed) was using Pennsylvania Brake for relined shoes and pads - they were right in the City - also closed now. :(
