Dana 80? please help!!!

[custommccannix]

i have acquired a full width dana 80. unfortunately it does not have anything on it just differential and housing. the casting identifier is 80 on the pumkin and the BOM is 6034490-4. i cant find this BOM anywhere the closest thing i can find is 603990-1 which is a Dana 60. could this be an actual Dana 60 with the cast on the pumkin just flawed. i have no ring gear to measure. if it is an 80 what hubs and parts will fit? i was told 60 hubs will work. it is a full floater and was told it came from a single rear wheel vehicle but the make and year had since been forgotten by the old man i acquired it from. the build dates are hardly there so im not put them in. someone please help i have plans on putting this axle in before summer and finishing the jeep. but i have a back up plan to use a toyota full width in casee i need to. thanks for your help in advance.

Checked my sources and the closest thing I can find is:
BOM - 603470-4 Which drops a 4 and is a 7 not a 9

Which would make it a:
JEEP Model 60 REAR 1979 - J20 PICKUP

Go here to search Dana's BOM:
Dana Holding Corporation - The Expert Axle Bill of Material

You can search by just the first few #'s if your not sure on the rest.

Also a link to the Dana 80 Maint. Manual which has ID info in it:

Just in case.

My neighbor had a Dana 80 under his Cummings 4X4 and that thing dwarfs a 60 so you should be able to tell the diffrence in a 60 and 80 just by its physical size and the attaching bolts on the cover

Dana 60 uses a
9 3/4" ring gear with 3 1/8" axle tubes

and the Dana 80 uses a
11 1/4" ring gear with a 4" axle tube.

Just take a few measurements and you should be able to tell what you have.

Both have 10 bolt covers.

sorry its been so long get back on my feet from surgery. the axle housing has 3 1/8" tubes. so i guess it is a dana 60 there is no signs of any sleeves in the differential housing to step it down from 4 to 3. anyone tell me the measurement from the brake mounting plate to the end of the spindle for dual or single rear wheels i was told this one was a single but without anything on it i am at a loss. thanks
