Polk RTA 12 B Grill Template

I am in the process of refurbishing my Polk RTA 12B's. They have received the royal treatment which includes rebuilt crossovers, t-nuts to mount the drivers, acoustic matt inside the cabinets, relocating the top crossover inside the cabinet, refinishing the cabinets in Cherry, custom made Cherry stands, and a custom solid Cherry tweeter mount.

My last piece of manufacturing will be a new speaker grill. Is there any way to get a template of the original wood grill dimensions and hole placements? I need to work up a drawing for a friend who works at a fabrication shop to cut the new pieces, but it would help to have dimensions. Thanks.

ps: I'll post pictures when we are done. Finish will be hand rubbed lacquer.
