Gathering parts for front disc brakes for 1969

[Accelo]

Glad you are up and running. Changing the brakes to disks is a much bigger job than most realize. You helped yourself out by doing the research. Rebuilding the proportioning valve instead of going new may have saved you a big headache. I couldn't get the first two to not leak! Third time was a charm.
I have no idea why someone can't come up with a plug and play system for retrofitting the C10's. The only ones available are the "Plug and Pray" systems.
Cheers and good job.
