Odd ball rear

Hi Guys
I am aware of the "fact" that Ford did not install Dana 80s in trucks until the 90s.
BUT
My '61 has this rear end in it. It looks like a 60 but..............
Just looking for a little knowledge.

1959/67 F100: If Limited Slip was ordered, Ford usually installed Dana 44's, but...

1963/66's were also available with the Dana 60.2 .. 1966/67's were also available with the Dana 60.3

Both also have Limited Slip, but are not Dana 60's that were only installed in F250's.

Dana rear axle ID tag located under two of the bolts that retains the inspection cover to the housing. Many are missing by now.

AXLE code stamped on the 2nd line-far right of the Warranty Plate, located (1961/62) on the inside of the glove box door.

1963/79: Warranty Plate located on the left door face below the latch.

Look at the vent plug on the axle tube. Used to be drivers side in the mid 60's and was made entirely of metal. Later model diffs used a plastic vent cap. Possibly a PO swapped for late model rear??? Just guessing..

E7TZ-4022-A (replaced 8A-4022 & C2OZ-4022-A) .. Rear Axle Vent-metal tube ~ Myriad 1948/89 FoMoCo vehicles.

OP's truck, if a 1961 F100, would have come w/a Dana 44 with Limited Slip or the Ford 9" that was not available with Limited Slip.

Since the rear axle has an inspection cover, it's not a 9 inch.

If you look at the 2nd photo there is a tube / hose in photo (guessing it is from the vent). Dana 80's (Im pretty sure) are newer than 89 and mostly in Dodge trucks?? If he has the vent tube with hose on it, these clipped to the frame and the vent itself is plastic. Our older vent tubes were a short item with metal mushroom looking cap, no extension hose. I totally agree its not a 9" rear!! Now, how he ended up with a Dana 80 housing and drum brakes....??? Beats me

Rear brake flexible hose has a hole in its brass block. The vent tube passes thru the block, threads into the rear axle.

Some trucks with Dana's and 9 inchers have a vent hose (what I see in pic) that routes from the vent tube up to a bracket that is attached to the right (passenger) side rear frame rail.

This keeps the vent hose from getting plugged up. This vent hose is just dangling.

I doubt that a Dana 80 has been swapped in. IMO, it's the original Dana 44.

Dana 80's were installed beginning in 1988 F53/59 Stripped Chassis & F(Super Duty), have an 11.25" ring gear, 16" 10 lug wheels on a 7.25" bolt circle, 11,000 lb. rear axle capacity.

According to this "chart" I found and your photos, sure looks to me like you have a Dana 80 in your truck. Hope this helps.

That Dana 80 inspection cover looks nothing like the OP's, as it's taller and narrower than the inspection cover in the OP's pic.

How the hell could the OP use his 5 lug, 5.50" bolt circle wheels on a Dana 80 that came with 16" 10 lug wheels on a 7.25" bolt circle?

Here's the Dana 80...does it resemble the rear axle in the OP's truck? Not to my eyes it doesn't.

ND - I did not know it has 5 lug wheels. I was only going from the photos and the 80 stamped into the casting which according to Dana Spicer indicates a Dana 80. As you know, all sorts of mods have been done to these trucks over the years, including the Crown Vic swaps, etc. Below is a pic of a supposed 61 with 8 lug wheels. Now I'm really interested to see what axle this is as Im sure you are as well.

Ok guys
Sorry that I couldn't get back on yesterday. I know it would have prevented some stuff.
But I have partially solved it because of Bills' slap on the noggin to check the vin plate, duh.
The center section is not shaped like the 80s that we are used to now days as they are much beefier.
It is a floater. Sorry for the miss info. I haven't had it apart in years and have had so many others apart lately I just miss remembered. I hate getting old.
The vin plate says the truck should have a 9 inch with 3.0s in it (A1).
So some PO must have stuffed this older 80 into it. The front is 5 lug.
My question now is, when did Dana start making 80s?
And why is it an 8 lug instead of ten?
I know 70s where first built in '58.
Can't find anything on 80s.
Had to get to work in a hurry this morning, so didn't have time to clean and check the tag. Will get to it.
Included a better shot of vent tube.
Pix below

From what I've read on different sites and some aftermarket sites, apparently (and I use that word with care) some folks claim there are Dana 80/70 hybrids using the 8 lug hubs. You never know what a PO has done, or the PO, PO, etc. If you've got 8 lug on back and 5 up front, enough said. But aftermarket sites are saying its possible (8 lug). The vent tube hose pic you show is missing the actual vent (cap). I tried posting a pic but somehow not working right now. Likely this will take some more Dick Tracy to get to the bottom of this one....best of luck.

PS...This could possibly (and I say this with all cautions) have come from a 2500 series 2 WD Dodge, single rear wheel. I could be very wrong, but my old memory from when I worked on trucks and cars for a living, I don't recall 10 lug Dodges. But my recollection is also muddied with time. Good luck.

Thanks, bet I'll have to get inside it to really see what's up.

Don't be sorry.
I keep telling myself to replace that sig but can't bring myself to do it.

Wonder how wide the Dodge frames are.
As you say, lots of fun detective work.
