looking for a right part that goes into where marked on the pic.
it's the arched bridge—found only on Carlton style frames—for the rear center pull brake assembly.
common barrel adjuster stuffs including Mickey adjuster sorta wouldn't work, too thick for the hole—about 5mm upper, 3mm lower.
will appreciate advices on:
1. what it's exactly called
2. whereabout to get such a thingy
3. any good 'alternative' idea
thanks!
