65 Chevy C10 rear drum brake woes. please help.

[grubsster]

You may need the parts you ordered. I don't know. However, there are many threads on this forum and in the Faq's that talk about converting to disc brakes, which include, relocating the pushrod hole at the pedal. Maybe the CPP guy is right...

All I can say is that many people on this forum have tried to help and, the simplest piece of advice from MikeN, BigElittleg64, and your own illustration in post #16, all point to push rod location modification. I would try that first before changing everything in the brake system.

Hope you get it figured out soon.
