I have a recently purchased 1979 Ford F-250 Custom. I want to install new gaskets on the differentials. It appears the rear one is a Ford 10.25" would the front be a Dana 60?? I can not find a tag on it yet.

Thanks for the help.

If the front diff cover has 1/2 inch bolts it is a 44, If has 9/16 its a 60.

 

It could be a factory installed D60, if your rig was optioned with the "Sno-Fighter" package.

 

Thanks guys, shouldn't there be a tag somewhere with the info?

There "should" be, but by now the tag is prolly long gone thanks to rust. If you take a wire brush to the front side of the axle you may be able to see some numbers. Unless someone swapped in a Sterling, your rear axle should be a Dana 60. Like JB said, check the bolts. That's the easiest way

 

It'll either be a 44 or a 60, like stated above check cover bolts 1/2"=44, 9/16"=60, or measure the hubs (if factory) 3 3/8"=44, 4 1/8"=60

 

Sterling 10.25" introduced in 1985.

Rear axle is a Dana 60, front could be a Dana 44 or a 60.

Dana axles: The Ford axle ID tag was under one of the bolts that retain the inspection cover to the housing.

Many are missing today, because peeps neglected to re-install them when re-installing the cover.

Dana 60: The Dana 2" x 1/2" ID tag is bolted to the housing (two bolts), adjacent to the inspection cover. Has a 7 or 8 digit Dana ID number stamped on it (examples: 603010-1 / 603010-11).

The AXLE code is stamped on the Warranty Plate, but usually it only refers to the rear axle. The 3rd digit, if present refers to the front...but if a J = Power Steering.

Most AXLE codes have no front driving info contained within (ratio/type of axle).

 

a dana 60 will have the number 60 on the housing itself. You may have to wire brush off some of the crud to see it

 

Thanks Gents, the tags are gone but I do know now that I have the 44 front and 60 rear.
