Need help identifying this 9"

[Pac8541]

Specs:
59.5" wms
3.25" tubes that step down to 3" towards the ends
3.09 gears
28 spline tapered shafts
11.5" disc brakes
5X5 bolt circle

Supposedly its got a posi inside but its draining right now so I haven't pulled the 3rd to look.

I've done some research and initially I thought maybe it came out of a Torino or Ranchero but the spline count is off for those, even though one axle flange has the 2 holes and countersunk center that is supposed to be indicative of a 31 spline shaft.

Help me out here you Ford guys.

Lincoln versailles dunno bout the 5 on 5 business though I think a versailles is 4.5 but not sure.

[Pac8541]

Well ok, but what I'm looking at for 9" axle widths shows the Versailles shorter than what I've got by 1 inch. Maybe what I'm looking at is incorrect? Here's the chart I'm using:http://dfwmotorsport.com/Fairlane/9inchrearends.htm

I am thinking fullsize Lincoln or T-bird due to the 5 on 5 bolt pattern.

Cant see any suspension mount clues- do you know how it was mounted?? (coils and links or leafs) coils would be the fullsize cars like I stated, leafs would be the versaille

[Pac8541]

It appears to have had leafs but the spring pads were removed and ground down before I got it. Based on the marks left on the tubes, it appears there were there though. No other suspension tabs, etc were on the housing.

One other measurement: tube end to tube end it tapes out to 55" (without brake brackets, etc).

[Quick & Dirty]

I have a disk rear from a 76 Lincoln Mark, which is a long wheelbase Torino platform. The WMS width is 63.5". It has the 5" pattern, but is too wide, and had a 4 link suspension with lots of brackets to grind off.

[Pac8541]

Did a Versailles or Lincoln come with a posi though? I wouldn't think so but I don't know.

Here's a look at the innards. Doesn't look like any of the pics I've found of a factory traction device but again, I could be looking at the wrong thing. Let me know what you guys think:

Could be wrong, but it does not appear to be any kind of a factory carrier, open or posi. All of the ones I have ever dealt with had a cast kind of texture to them. The adjuster locks are missing too, further making me believe that someone has put something good in there- as far as what, I do'nt know.

[82F100SWB]

That looks suspiciously like a detroit to me for some reason.... I'll bet those are aftermarket gears too.

[Pac8541]

If that is the case, it will salvage what was appearing to have been me getting played. It was supposed to have come with 31 spline shafts (advertised) but what came out were 28's. It was supposed to have had a 1310 yoke installed, but that didn't get done in time. Now the seller is not answering his phone nor returning my calls. He got his money so what does he care....

[Pac8541]

Well its some kind of locker but I don't know what exactly. The photos I've found of the factory Ford Equa Lock and Trac Lock show clutch plates and a different style carrier with recessed bolt holes for the ring gear. This carrier looks like an open carrier on the outside but has a toothed steel locker similar in appearance to a Lock Right with 2 heavy springs holding it all together. Too bad its not a detroit but the damn thing is a 28 spline unit anyway so its not much good to me.

it looks like an early detroit, but it wanst called a detroit. my 68 bronco had 28 spline and a locker that looked just like that - my great uncle had it since it was new - it was a dealer installed ( he owned the dealership ) - the housing looks like an early t bird -

Interesting. Any idea who would be interested in such a beast? Are these at all desirable among the muscle car crowd? Thanks for the info.

[Quick & Dirty]

Detroit Automotive Products No-Spin locking differential. That's the official name from an old Ford service manual.

[Pac8541]

Fantastic, thank you!

[mustange70]

That look to be a lincoln 9" with that bastard sized ring gear they used (the 9.75" ring gear or something like that), cause the housing is notched on the top in the one picture and that tells me its that odd ball sized ring gear, and those disc brake brackets are definately lincoln, as i have the same set back home.

[Pac8541]

Well the ring gear measures out to 9" across the toothed side so....

[MedwayJunkyard]

Did they grind the numbers off the axles tubes? I might be able to look those up in a hollander manual.

[GMCTruxrule]

Identify this 9.....:D

Tell me where to look on the tubes and I'll see if I can find them tomorrow. Just made some guy locally very happy by selling him the complete 3rd. I have a feeling I underestimated its value and the guy got a screaming deal.

1937 ford?

Smells of Lincoln to me...

Right... but it doesn't have the curved upper rib on the pig that identifies it as the 9 3/8".

They did make one around that size. It was for an airplane tow.

X2, both of the 9 3/8 that i have had came out of 1972 F-100 4X4s with 360ci and 4spd's. They both also had 4.20 gears in the rear and 4.10's in the front which i found very odd, most manufacturers wont run gears with that much offset.

[Totalled]

Odd. The last one I saw was under a '72ish F-100 with 3.50 gears and L/S.

[mustange70]

I stand corrected on the 9 3/8", i have one one out of a lincoln markiv (or v can't remember as its been a while since i pulled the rear out the car) that had the disc brakes and such.

Ah ha! Eye for the old iron!

The numbers on the third member, assuming it fit the case, and was original to it. Were your best I.D. numbers. Ford's part numbers usually tell you the year, and at times the model line.

Example I have a 429 from a 69 T-bird. The heads are C9VE. A 1970 429 with basically the same heads will have D0VE (Zero not the letter O). C9=1969 D0=1970. I'm not a 9 inch expert, yet was thinking the axle tubes or the housing should have a stamping in/on it somewhere. The Axles should have a part number on them.

Pre-1962/1963 Ford parts do not have the date codes in the part numbers.

The date codes on part numbers are not always accurate. They only show you the year the part was designed for, and can run in many models afterwards. In other words, D3TC rad supports and grill shells could be found up to 1975 model years, and D3VE 460 heads might be found up to 1975 model year or later. The only thing the part number tells you for sure is that it couldn't have been on a pre-dated model. I believe the marker and tail light lenses all the way up to 79 carried the D3T* part number.

The part numbers can tell you the Vehicle type, and base year. With this info you can find the correct parts such as axle seals, wheel bearings, ect.
