AFAIK center-pull is a type of caliper brake, and doesn't use frame/fork mounted brake bosses.
Canti- and v-brakes generally use the same brake boss spacing, with some old frames/forks/brakes using a tighter spacing.
Then there is the U-brake. Generally found on BMXes and a handful of MTBs.
I guess it's this you're asking about. Unfortunately I can't help you there.
