If you are really into the detail end of the 65-66 Mustang and Shelbys, you may find this post interesting. A Kelsey Hayes disc brake proportioning valve was originally installed on the 65-66 Mustangs with factory front disc brakes.
Rather than discuss the function of this part, this post is more about the detail and restoration. There seems to be a widely held thought that this valve was originally a bluish-gray color. All of the New Old Stock / Ford Service parts that I have seen are certainly this color, and perhaps some of the ones originally installed on the assembly line were also this color.

I do have evidence though, that at least some of these valves were originally finished in black paint. I have seen several other original examples that were black, including the one on
an early '66 GT350 (SFM6S033). This GT350 will be featured here on our Virginia Classic Mustang Blog soon. I have also seen a black one on a much later production '66 GT350 (near the very end of the '66 GT350 production.)
The "end discs" on these valves are dated. The numbers indicate the day of the year along with the year.

Jeremy at Maple Hill Restoration did the paint work on this. He also does the restoration work on the
1965 Mustang 289 HiPo convertible that is featured on our Blog. He will soon start on our
Carryover 1966 GT350 Shelby. You can contact Jeremy here.

Your comments re: the 65-66 Mustang DBP valve are very interesting. At 86 & after
having many early Mustangs, some I wish I still had. (66GT FB Pony, 66A Code CP Pony & a 66GT350 Green Shelby FB)I still have some used & NOS parts left. I found 1 item, a KH DBP valve #56653 in blue base color. 42-0 on the end. Is still in the sealed clear plastic bag, never opened, some parts I used & some I still have. Most of my cars were 1 owners from the middle 70's. All needing something. Thus the trips to local Ford dealer & the local junk yards. My wife & our 3 boys all had some of my more rare Mustangs to drive while in HS. I even got published in one of the very early & small Mustang Monthly mags. Well Thanks for listening. My DBP valve will be for sale soon. Regards, John
Does anyone know where I can get the heavy spring in the 65-66 Kelsy-Hayes proportioning valve? 1970 may be the same except needing shortened. I really need one. Jim Thomas jthomas427@sbcglobal.net

I just removed one from my 66 GT A-code . unmolested car from Dearborn plant , family owned since 1968 .It is the bluish - grey color
Depending upon the production plant and production time, you may see black or the blue/gray color on these. Thank you for the comments!
This would fit on 1966 Lincoln continental coupe
