The 9 3/8" rear end was standard equipment on 1968/72 F100 Camper Specials.
D0TZ-4010-A .. Axle Housing / Fits: 1968/72 F100 w/a 9 3/8" Ring Gear.
D0TZ-1225-A .. Axle Bearing / Fits: 1968/72 F100 w/a 9 3/8" Ring Gear.
9 3/8" = This is the only F100 that used these axle bearings.
------------------------------------------------------------
C8TZ-4010-A .. Axle Housing / Fits: 1968/69 F100 w/a 9" Ring Gear
D0TZ-4010-B .. Axle Housing / Fits: 1970/72 F100 w/a 9" Ring Gear.
C9AZ-1225-A .. Axle Bearing / Fits: 1957/86 F100/150 w/a 9" Ring Gear.
(C9AZ-1225-A replaced C1SZ-1225-A & B7A-1225-A).
----------------------------------------------------
If the parts were the same, the part numbers would be the same.
As y'all can see...they are not the same.
Internally only the two pinion bearings are the same between the 9" and 9 3/8" rear end.
Everything else is different. EVERYTHING!

I put a 9 3/8" pumpkin into the 9" housing of my '67 390, 4-speed Mustang. Only thing I did was notch the housing and use the Mustang axles.
My '72 F100 short bed has a 9 3/8" diff from the factory; the housing is notched from the factory to accomodate the larger ring gear.
The different part numbers for the different housings reflect the notched and non-notched housings.

I have put a 9" center section in a 9 3/8" case in my 66 Galaxie. The center section was out of my 68 Mustang and was put in for it's better gear ratio and trac loc. I did this well over 20 years ago, nobody even knew what a 9 3/8" rear was, most still don't, and it has been in there ever since, works fine except I would like to change it out to a more mileage friendly ratio now. Getting older sure changes the priorities. I didn't have to change any bearings in center section or axles.

Not that it matters in my case but the only mods vice versa would be the notching needed to put the 9-3/8" center into the 9" rear end housing. Thats probably really rare to ever see that anyways. Thanks for all the help.
