Looking for some info or part# on the spring that should come from the cable adjuster back to a cross-member ? I seen a pic of one yesterday, wish I would of saved it, so I made a pic up below....... 76' f250 4x4 standard cab, guess that is called the equalizer spring ? Lil MS paint action simulated spring in red
Looked up the part on my parts CD as I have a 76 also. From what I can tell, depends on serial number. C7TZ-2A651-B if before serial# Y40000. D3TZ-2A651-A after serial# Y40000. Not an expert, just tryin to help.
My Ford parts book essentially shows what Hickory 1991 found:
C7TZ 2A651-B Spring (equalizer) Before ser. Y40,001
D3TZ 2A651-A Spring (equalizer) From ser. Y40,001 to ser. Y60,001
The C5ZZ 2A651-A is likely for an older truck or different chassis. It "might" be able to be made to work if the "spring rate & length" is similar, but you may have to change its overall length.
Do you have the original spring for your truck? (even if it is damaged).
My truck is a '76 F-250 2WD regular cab, which uses a D2TZ 2A651-C, so it probably wouldn't do much good to measure it.
It will likely require Bill (Number Dummy) to resolve the question. He may also have a source for you.
In the mean time you could check your serial number. Then you would know which is the correct part number.
How exactly does the serial number correspond with the VIN ? (I know that's a dumb question but im overdue for a couple ) Also there are a few aftermarket websites that have C5ZZ-2A651-A fitting our trucks, but originally a mustang part# ................. The original spring is long gone, never seen it, didnt realize it took a spring until I came across a picture of one.... Maybes its time for me to buy the Parts CD..... I seem to run into a wild goose chase with every little project
May have to see if the one you found will work. I did a little searching and no obsolete parts vendors has any. The parts CD was helpful during my resto job, but took me a while to figure out how to use it correctly.

Those of us that choose to have an old car/truck hobby seem to frequently have to deal with "chasing" old parts. It just "goes with the territory". The parts CD would probably help. I bought the parts book years ago, and it has helped me (though it was expensive). There are businesses across the country that retain the old parts long after the Ford dealers have ceased. Often if I go to the Ford dealers, my inquiry brings a lot of humor to the personnel. They say:"You want a what for a what?". Some of the more popular parts have been manufactured anew due to the demand. One of them "might" be a help to you. You should probably check out LMCtruck.com. I have one of their old catalogs from 2015 Fall. On page 112 it shows a parking brake spring for the 1976-79 F-250 4WD with serial number Y60,001 & up for $9.95 + shipping. I can't tell if it's the one you need.
The 1976 Ford truck shop manual calls the last part of the VIN the "consecutive unit number". This makes me think that it should be the "serial number". Sometime terminology and numbers can be exasperating.

'76 F250 4x4 Regular(not a Crew) Cab, guess that is called the equalizer spring.
C7TZ-2A651-B .. Equalizer Spring - 24 1/8" long / Obsolete ~ No Ford dealer or obsolete parts vendor has any.
1967 F250 4WD from serial number B12,001 / 1968/76 F250 4WD / 1977 F250 4WD before serial number Y40,001.
Serial number is the last 6 digits of the VIN
------------------------------------------------ C5ZZ-2A651-A .. Equalizer Spring - 15 1/8" long w/25 coils is not listed in the 1964/72 or 1973/79 truck parts catalogs.
It's listed in the 1965/72 Ford Passenger Car Parts Catalog for 1965/68 Mustang.
Thanks Bill, that clears some things up, I suspect folks have been using the mustang spring in place of the truck one..... I will try to find something comparable.........
In case anyone ever is searching and finds this thread here is the pic, it does exist ! Just cant find one
After a diligent search, if it proves to be impossible to find, you may be able to fabricate one using another that has a similar coil (using the photo as a guide). If it pulls the cable back sufficiently, it will keep the brakes from dragging.
Here are a few salvage yards that claim to have a 1976 Ford F-250 in their inventory with the parking brake available. It may be that they won't want to sell just the spring, but I thought that I'd show them anyway if you wanted to call them. Also, only the last one said it was RWD. The others didn't specify the drive or cab type.
