Default Proportioning valve source?

OK team, I am feeling lazy so can any of you fine chaps point me in the right direction for a new brake proportioning valve for my '66 Town Landau 'bird?
I did have a look at Rockauto but didn't see one listed.

There isn't a new replacement for your original proportioning valve. Newer replacement valves are designed for a dual master cylinder. If you want to stay with the single master cylinder then I would contact the TBird vendors that sell used parts and see if they have a good used one. There is a rebuild kit available if you want to rebuild your old one.

You can use any single line adjustable proportioning valve.

How do you use a single line valve to replace the stock valve that has multiple outputs?

I bought my combination valve for my dual master cylinder from Carolina Classic Trucks.

You keep the stock manifold and just use a P-valve on the rear brake line.

This explains how a combination valve works, which has a metering valve section and a proportioning valve section. My set-up lacks the metering valve, so I get a little bit of front brake grab during light stops. I minimize this by frequent manual adjustments of the rear brake pads.

Are you also changing out from a single reservoir?

Not at this stage, getting into 'mission creep' too much as it is!
