D0TA-AS was built with originally:
3.73 ratio. Parts list #93 which is for an Open, Non-locking axle. 1969 after serial number F30,001 to 1972 F250. 12" X 2 1/2" brakes. 16 spline axles.
1957/72 Ford F100 9" will work on 1948/52 F1 & 1953/56 F100 (originally came with Spicer/Dana 35's and 44's).
1956/72 F250 Dana 60 will work on 1948/52 F2 & 1953/55 F250 (original came with Timken rear axles).
Ford increased the width of the 2WD inner frame rails behind the cab in 1973 from 33 1/2" to 37 1/2" .. so these rear axles are too wide.
Note: 1956/65 F250's have 12 1/8" x 2" front/rear drum brakes. 12" x 2 1/2" front/rear drum brakes introduced in 1966.
12" x 2 1/2" brakes standard equipment on Camper Specials and 7,500 lbs. GVWR non Camper Specials. 1966/72 F250's under 7,500 lbs. GVWR have 12 1/8" x 2" brakes.
There is a hole in the axle flange between the wheel studes to remove the clamp that holds the axle in place. Is there a clip in the carrier that hols the axle in place?
A side note, the brake shoes are 1-3/4 inch. Impossible.
46-13: The rear axle ratio is 3.54-1 but there's no such thing as any F250 or Dana 60 with 11" x 1 3/4" rear brake shoes.
Considering the 3.54 ratio and the 11" x 1 3/4" rear brakes: What your truck has is a Dana 60.3 from a 1966/67 F100. All F100's thru 1979 have 5 lug wheels on a 5.50" bolt circle.
The Dana 60.3 offered two ratios: 3.54-1 & 4.10-1. This rear axle also has Limited Slip. Only F250's came with a Dana 60.
All 1948/52 F1's, 1953/67 F100's have 11" x 1 3/4" rear brakes.
1956/65 F250's have 12 1/8" x 2" front/rear shoes as do some 1966/72 F250's.
1966/72: F250 Camper Specials and F250's with a GVWR of 7,500 lbs. have 12" x 2 1/2" front/rear brakes.
1968/72 F250 2WD's with optional dual piston caliper front disc brakes have 12" x 2 1/2" rear brakes.
I just crawled back under the truck to look at the top of the dif. I rembered there was an other casted number with the 60.
The axle is a dana 60-2. I bought it from a guy who said He thought it had come from a 1960 f100, but at that age it could have come from any year.
So i spent time looking at dana 60 not realizing the dana 60-2 and dana 60-3 are completly different, That must be why there is no BOM number.
So i found out the dana 60-2 is a 16 spline axle for the years 63 t0 66. Is that info correct?

The axle is a dana 60.2 I bought it from a guy who said he thought it had come from a 1960 f100, but at that age it could have come from any year.

So i found out the dana 60.2 is a 16 spline axle for the years 63 to 66. Is that info correct? The axle shaft spline count isn't correct.
Dana 60.2 (1963/66 F100) also available with 3.54 & 4.10 ratios and also has Limited Slip.
The axle shafts (C4TZ-4234-C right/left same) have 30 splines.
1961/67: The large ball type axle bearings (D8AZ-1225-C replaced C1SZ-1225-A & C9AZ-1225-A) are the same as 9 inch; Dana 60.2/Dana 60.3.
In fact, they're the same with 9 inch: 1961/72 Thunderbird; 1961/83 F100; 1966/86 Bronco; 1975/86 F150; 1975/87 E100/150.
Note: There's also a medium ball type bearing, but not for these trucks. Some 1974/79 F100's & 1975/79 F150's have a tapered roller bearing/seal combination (D4AZ-1225-A).
There is a hole in the axle flange between the wheel studes to remove the clamp that holds the axle in place. Is there a clip in the carrier that hols the axle in place?
Thanks
All 53-56 F100s came with Dana 44. Ford didn't put an identification tag on them like later years. Just a Ratio Tag. These axles were parts list 65. The ratio 3.54 is not listed in parts list 65. Just 3.73, 3.92, 4.09, and 4.27. So what rear axle you have I dunno.
The Dana 44 did have a hole in the axle flange like a Ford 9". And also a press on collar for the axle bearing that held the axle in just like a 9". No clip inside held the axle. 1948/56 F100 Dana 44s had an axle bearing stamped 88128. This is an industry number. Not just Ford or Dana. Any big box parts store or bearing company should be able to work with that number. IF THAT IS WHAT YOUR AXLE HAS. It was 1 17/32" I.D and 3 5/32" O.D.

The ratio 3.54 is not listed in parts list 65. Just 3.73, 3.92, 4.09, and 4.27.

El Jeffe: The OP's thread was by the member in post #7. I responded to this post (see post #9), then realized it wasn't the OP that asked the questions.
Since the rear brakes are 11" x 1 3/4" with the 3.54-1 ratio, I initially I thought it was a Dana 60.3 from a 1966/67 F100.
But this member found Dana 60.2 stamped on it (see posts #10 & 11), so it's from a 1963/66 F100.
Threads that are hijacked cause mass confusion, to say the least.
@TA455HO Hey, Thanks for your help. Wanted to stop my hijack of the brake cable post, so moved here. I did find the rear end code - it was buried pretty good and faint.
Date code is 9 14 1 B6 I haven't been able to make sense of this - Any ideas?
BOM is 603195-5. I was not able to find this on axlebuilder.com, but found it in this post and in a Spicer catalog via manualsdir.com shown below. Shown as 71-72 F250 w/ 3.73 gears.
I have 4.10 gears by my count and by info from my PO. PO also suggested it was late 60's, but that seems incorrect. I'm not sure why it was swapped by PO.
The same Spicer catalog has an exploded view of the rear end, but does not show the axle bolts - so doesn't help with the mystery of cones / no cones. Possibly the axels are out of a different rear end.
My front axle is going to be harder to find the code - I'll look into it this weekend, but I was wondering if you know a good path to get limited slip into the front, which currently has regular 4.10 gears and is closed knuckle
