Default proportioning valve instal

Does anyone have a picture how to install a adjustable proportioning valve in a 69, power brake, Fwd disc and Aft drum?

Anywhere between the distribution block and the rear axle on the 3/16 brake line. If you have an original front disc brake car, why are you adding the adjustable valve? Your distribution block should already have rear wheel proportioning built in. No need for a second valve?
Best,
Al

Al is right, your factory disc/drum should be equipped with one.

I know, I have already one. But it looks crap...don't know if it still working because I have an unbalanced braking.
I have seen some repair kit like this one

1968 - 1969 Mercury Cougar / Ford Mustang / Torino Disc Brake Proportioning Valve / Distribution Block Seal & Rebuild Kit - New (5302) at West Coast Classic Cougar, inc. :: Specializing in 1967, 1968, 1969, 1970, 1971, 1972, and 1973 Mercury Cougars

What do you think?
Keep the original? The original valve is per-set for the balancing, right?
Using an adjustable valve could help to have a more precise adjustment

This is what I have seen somewhere here. The thread was talking about the original valve, it was not working anymore. So the guy had replaced by new parts

SR,
This is how I installed mine (Ford Racing).




I added two 10/32 x 2" stand-offs through the mounting holes to the inner fender.
These....
McMaster-Carr
& used some stainless screws.

Mine's under the hood by the distribution block. The last disc/drum job I did on a buddy's GT-350 clone I put a lever style under the dash. I've also installed them in front of the driver's seat and in the trans tunnel.

i made an L shaped bracket and bolted it to the rght side of the master cyl., and attahced the proportioning valve to it. Then I made a small bracket for the line lock and used the original proportioning valve bolt holes to mount it there. I like to modify the car, but I try hard not to cut or drill extra holes anywhere. That way if someone wants to go back all stock its not gonna be to hard. Its a k code gt fb automatic car.

thanks to everyone!
So what would be your advices now? replaced the original by an adjustable or keep it like this, while restoring the valve?
what would be the best choice?

It depends on what shape your original proportioning valve is currently in. I had one on my 65 that started leaking, so I went ahead and bought one of those kits you posted a link to, but the PV still leaked after I installed it. Those things aren't free, either. I ended up buying an adjustable PV, and haven't had any problems since. I wanted to keep the original PV, since it was an original, but guess it wasn't in the cards for me.

Good feedback...
So it's better to go for a brand new part, instead of trying to rebuild a old c***
