'69 Manual Master Cylinder (Disc/Drum) Bore Size
 

What would the correct bore size be for a 1969 pickup with a manual disc/drum setup?

Also, what master cylinder would you recommend for this setup? The individual is looking to cleanup under the good and would like a proportioning valve mounted up under the master cylinder.

I believe it's 1" bore iirc.

1" is what I would use.
Aluminum only!

Based on what I have researched, these trucks only came with 1 1/8 bore for manual and power disk/drum. Most people, myself included use a Corvette master, which is a 1" bore. POL has an aluminum Corvette MC and the prop valve can be mounted under the MC or to the side like factory.

Thanks for the info.

He just located the CPP version with the built in proportioning valve. So we'll see where we end up. :)
