Been kinda busy, here is what I have so far.
57-67 F100, P100, Both axles the same at 30"
68-69 F100 28 spline and 70-72 with 28 splines; both at 29 15/16"
As above but 31 splines both 29 13/16"
73 and later they got a lot longer.
Rear
Drums:
11" with 1 3/4 shoes
66-75 Bronco
53-67 F and P100
49-51 Merc
59 F100 4x4
No shoe info but the same drum:
68-74 F100
68-74 E200
75-early 76 E100 & 150
75 early 76 F100 & 150
I can keep digging as time permits, what do you want next?

Excellent, Carl! Now if you can get the same info for the '77-'79 Thunderbird, Cougar, Ranchero, and LTD II, we'll be able to draw some conclusions. I think we're most interested in the driver's side. Apparently there is a difference in lengths between the pass. and driver side. I believe that all the above vehicles had the same rear ends, axles, and brakes, but I'm sure you'll tell us if they're not. Thanks for the help!

Thanks Carl, that is very helpful. If the swap is a good one, we are going to see if Joe will go pull a couple dozen of them for all of us on the board. The axle length info for the car applications Joe mentioned should pretty much resolve the issue one way or another.

I found a 9" the other day. I don't know what it came out of though. One side was about 3-4 inches longer than the other, therefore the carrier was offset to one side by the same amount. Is this normal? If I use it, the drive shaft will not be in line with the transmission. I know there are U joints but I would think the constant angle between transmission and rear end would not be good. Should I pass on this one. It is $150 and everything is there. Paul

Actually the offset angle is good for the u-joint. If it is too straight, the bearings don't move and as a result don't receive the lube they need.
When you install a driveshaft you must have between 1 and 3 degrees of angle. I believe the max allowable is somewhere around 13* before you start causing severe damage to the joints.
Crazy, huh?!

Yes if is fine if it is offset. They should ba parallel though. Beolw is Niolons website. Good article.

First, a minor correction in my earlier post.
The F100 31 spline is 70-72 only, my post would leave you to believe they had 31 spline for all years....sorry.
So here goes with your order Joe:
Drum brakes only for ALL listings
Right axle 33 1/4"
Left axle 30 19/32"
73-78 full size Ford
73-78 Lincoln
79 Lincoln with 1/2" brake plate holes
73-78 Mercury
NOTE: Include oil seal when interchanging between ball and roller bearings.
Right axle 32 7/16"
Left axle 29 51/64"
Note 1: Both ball and tapered bearings are used and will interchange by including bearing, cup, seal and bearing retainer
Note 2: Some Police/Taxi had a 5" bolt circle.
74-79 Cougar
77-79 LTD II
73-76 Montego with 4 1/2" bolt circle
77-79 TBird
73-76 Torino with 4 1/2" BC
Ranchero not listed as a model. Same as Torino??
Ya'all want more? Im on a roll here

That's great, Carl! You've confirmed what we wanted to know. The T-Bird, Cougar, LTD II left axle is within a quarter of an inch of both axles in the '57-'72 truck 9" assuming 28 splines. Since the 9" uses external axle retainers, this quarter inch may not present any problems so long as there is adequate spline mesh in the spider gears. Now the only wildcard is whether or not you can take the car backing plates and drums and bolt this all together and make it work. I think that's going to end up being a try it and see affair.

Thanks for all your effort. Yes a Ranchero should be the same as a Torino in the 70's. It looks like some of the car axles are about 1/2 inch wider. Assuming this half inch is in the drum area should mean it will work. If the difference is inside the rearend, then of course it's bad news.
I am not encouraged by the fact that the common 77-79 T-bird/Cougar has a shorter axle, yet there brake shoes are wider on the car. This does not sound promising to me. I think I will pull one at a salvage yard if nobody beats me to it. That is the only way we are going to know for sure.

Well, I finally got around to cleaning out the storage barn last night and I got the old man's crusty Cougar dug out and limped it back to the shop. Hopefully the weekend after New Year's I'll get it inside and drag the left axle out of it and see how it fits in the '72 F-100 housing. Stay tuned for the verdict.......

Joe's post reminded me to go look at the Lincoln axles that I had stashed. These axles came from a big Lincoln from the early 80's I think. The rear-end had disk brakes.
Measuring from the axle flange to the splined end of the axle, 29 7/16" and 31 7/8". 5" bolt circle, 28 splines, roller bearings.
The differential has 12 teeth on the pinion and 39 teeth on the ring - 3.25:1 ratio. Because this was a Lincoln axle, I had assumed that it was a 9 3/8" carrier, but now that I know the ratio is 3.25:1 I'm guessing that it's a 9". Does anybody know how to tell the difference? I'll go measure but I'm not sure that will tell me what I need to know. It also has a sensor, probably a speed sensor, on the pinion carrier.

How about the wheel bearing diameter on these axles? I believe the
57 - 59 (maybe later) passenger cars had a smaller bearing size than
the pickup. However, the retractable hardtop, t-bird, station
wagons, and ranchero had the larger bearing. I have never measured the length of the above car axles vs. the f-100 on these years
(or compared the splines) but it might be worth checking out.

The F100 bearing is larger than the basic car (see below)
but is also used on all Mercs as well as Lincoln, Edsel,GMC, Caddy, Olds, Pontiac, Packard; some as far back as 37 and at least thru 68.
As far as Ford cars, Hollanders says ALL with the large bearing 57 to at least 68.
The large bearing is described as used only in axle assemblies with 7/16" diameter brake backing plate bolts.
So it appears that even the standard car had axle choices based on maybe engine? Anyone have option catalogs?
As far as Ford family only is concerned, the large bearing:
48-67 F1-F100
60-67 P-100
49-56 SD & SW
55-57 TBird
56-58 Continental
57-68 passenger (as noted above)
66-68 Bronco with 3500 lb axle
58 Edsel
59-60 Edsel SW
55-60 Lincoln
55-59 Merc
60-63 Merc with big bearing
64 Merc all
65 Merc with large bearing
66-68 Merc all
I only checked my 35-68 Hollanders, probably used in later also.
Didnt get to the axle, ate too much food, getting tired!
Going to bed early and wait for the blizzard to knock out the power.
Merry Christmas from New Hampshire.
