I'm installing a 67 master cylinder on my 66. Is the rear outlet on the master cylinder (closest to firewall) for the front or rear brakes? Do I need to use a proportioning valve or will it be fine without? Thanks!

Matt,

If you stick with the drum brakes you don't need a proportioning valve. It's easy, but use the single master cylinder's push rod to the brake pedal. The '67 pushrod is too short. Good luck,

I pulled a nice clean distribution block off a 67 w/ 4 wheel drums and I was looking for a proportioning valve but didn't see one. That makes sense that I don't need one, if Ford didn't use one originally. After looking it over I've about decided that I could even use my 66 distribution block. Not sure what's best, I've read that people like to run the rear brake line straight into the 67 master cylinder, seems like a simple way to go. I doubt that one way works any better than another, as long as the system is bled out well...

I was installing new wheel cylinders on the front of my car and the plate that they bolt to was in pretty rough shape. Does anyone know what those metal plates are called and if repros are available? They bolt to the spindle w/4 studs. I didn't see them in a NPD catalog. Thanks.

they are called backing plates, & I do not think they are repoed. You would have to pull them from a parts car or from a wrek in a junk yard.

I wouldn't take the backing plate off unless it is rusted to beat He**. If the threaded holes are screwed on it and the rust is scaling off, go ahead. What you will find on junk cars won't be pretty either.
I pulled brakes, lines, backing plates, cylinders off a junk '65 car with new brakes(don't ask) this summer. So I have a set of plates here(somewhere) if you really want a set. Let me know.
