So in making the brake cables I noticed there is one piece that is needed for the yoke. It also appears to have application on the late brake handle (thats all Ive been able to check so far). It should work for early also.
Looks like they fit at the calipers also.
So one more item now (or at least in a few days) available.
$3.99 each and Im throwing in a stainless E clip. I will be stocking the spring retainer clips as an add on for those that value the OEM setup.
