Hello Everyone!
I have a '72 AMC Gremlin X, 258 6cyl, 3 speed stick, manual everything.
In process of upgrading to front discs from drums.
I'm using Scarebird brackets,
'90 Chev Celebrity calipers
'72 Gremlin manual disc master cylinder
'76 Camaro hoses
'72 Gremlin stock rear drums
Hardlines front to back will all be replaced.

My question is - what proportioning valve should I use?

The Celebrity calipers are single piston.
The rear wheel cylinders are 7/8 diameter
The master cylinder is a 1 inch bore
The car weighs 2600 pounds
Gremlins are front-heavy, about 60 to 40 front to back.

My thoughts were either the Celebrity valve, or from an S-'10 pickup.
I welcome any thoughts, ideas, or conversations on this topic.
It'd be great if someone here has done it.

Thanks,
Jeff
