BDB told me the M12 would work with with Paul Cantis. It looks like it will, but not without spacers at the fork crown mount and slight bending the struts, and even then it would be a slight rearward tilt. I would normally do it and not mind the slight tilt, but can't do it for this frame project. I should've just followed this List's suggestion to stick with Tektro CR720s. So I'm going to have to sell it...
Neo Retro front, Touring Canti rear, polished silver, tektro alloy hangers, no straddle cable though $135 shipped CONUS for the pair.
Paul Brake levers (pair), polished silver, short pull for road calipers, cantilever brakes, road disc, etc. Will not work for V-brake types. Almost new, couple of rides $88 shipped CONUS
Hunter Nugz, these are brake cable adjusters specifically for Paul Brakes. Almost new. Looks like you can't buy these anymore?

Paul Rack Adapters, brand new $20 shipped conus
I'll update with pictures when I get home after work.
