KELSEY HAYES PROPORTIONING VALVE KIT SOURCE

No reason to get huffy. But I am telling you that 1967 cars, which I am familiar with (had 3), and as well as the 68 and 69 cars, use a different proportioning valve which is separate from the metering block/safety switch and has an adjustable knob on it. The picture you posted shows the later style with integrated proportioning valve. My understanding is that the kit you mentioned is correct for the block you showed. What I was unclear on was whether the change to the integrated style took place in 1970, or in 1973 when the brake rotors and calipers changed. If his 71 has that style, then it would be correct.

Well, suit yourself.
Tried to help, with my reply...
No such thing as an "adjustable" proportioning valve on any of the A body line of cars, so i haven't got a clue what your talking about.

If you do have a 71, and then the "factory" valve will be this one.
And this valve was used from 70-76 on the A body line of cars.
