so we need a wheel cylinder for the ford 9" axle thats under our 54 F100 pickup here in the shop behind me.


i need to find out if there were any differences in parts on these axles in the mid late 60s to early mid 70s years

i have no idea what year make model this 9" is from

i cant find any leftover evidence of the spring pads being removed and welded relocated on these axle tube housings

were the 54 ford pickup leaf pack spacing the same as any of the later generations of the pickups,(in which one could be taken and bolted as is under this 54) and without any welding or mods like such??

under this truck it is currently:

54"(roughly)wide from backing plate to backing plate

40"(roughly) leaf pack separation distance, is this correct factory dimension for these trucks?


brakes are 11 x 2.5"(roughly)

wheel bolt stud pattern is 5 on 5 1/2" with small diameter studs
so apparently it cant be from a mustang etc since they are 4 1/2" bolt pattern..... hmm...



what year and model would this axle most likely be from?

he doesnt remember what they took it from, its been a longgggggggggg time ago when they did it


i dont know my fords anywhere as well as my chevy trucks, in which i virtually know all the years and all the(minor and major)changes and redesigns and dimensions of the axles springs and chassies, in my head, by heart

on the ford trucks i just know many of the basics, but not tons of them, esepcially not the 50s stuff

we've had this '54 for about 25 or 30 years now, since before i can even remember

we drove it into the shop tonight earlier to do some things to it, mainly to get the brakes working again, it still runs drives great fine, has a nice running '70s 2bbl bone stock 302 engine and matching C-6 and the chassis and brakes and all are bone stock non modified except for the custom engine mounts welded up from steel tube and angle iron real clean job though, and the exhaust headers and exhaust and floor mounted auto trans shifter from a late '60s or early 70s car of some kind




the only thing ive found on the net so far is this:

--------------------------------
The “rough" widths I keep in mind for Mustangs are the following: 52” for 1965 to 1966 (the same width as 64-65 Falcons
and 62 to 65 Fairlanes)(as in the Mustang line, most however never received a factory 9 inch), 54” for 1967 to 1970
(same as 66 to 69 Fairlane,Torino,Comet & Cyclone non station wagons)*cars with 351 and up engines received 9 inch
units-as did some 302 4V cars-(mainly GT's in 68 with optional gear ratios)* and 56” for the 1971 to 1973
Mustangs/Cougars- (cars with 351 engines and up receiving the 9” housings).Keep in mind as mentioned,
the Fairlane spring perch distances were not the same as the Mustang. All the Galaxies I have seen from throughout
the 1960’s used the 9 inch rear, regardless of engine size.
---------------------------------------------

1971 – 73 Mustang & Cougar. 9” , but lightest duty of the 9” family.
- Have the 5 on 4 ½” pattern
- Measures 60” flange to flange
- Measures 54 – 55” backing plate to backing plate.
- Comes with both 28 spline axles (weaker) and 31 spline axles (stronger)
- Oval hole in outer end of axle = 28 spline
- 2 large holes and counter-sunk center = 31 spline
- Number 2 choice for ease of installation and price.
-------------------------

1960-64 Ford Galaxie 9” medium duty
- Measures 54” flange to flange (?)

thanks for anything

Pull a wheel cylinder off. Take it with you to the parts house (along with a caliper for the bore diameter) and match it up to what fits. Write down the part number for future reference.

According to the info I have a 66-77 Bronco housing width is 52 1/4". I believe they would have had the 5 on 5 1/2 bolt pattern.
