Hi, I'm restoring an old Miyata 615 touring bike that came with some Dia Compe 983 canti brakes. The position of the cantilevers is unusual to me because they are facing downwards when tensioned, whereas I'm more used to the cantilevers facing "upwards" on other old mountain bikes I have. Because of this positioning, I'm not sure how to achieve the optimal "L" angle between the straddle wire and the cantilever. Any thoughts on whether I should move the yoke up or down?

Excuse the wires, those will all be fixed eventually. Wish I could say the same about the fork...
