Need help axle identification!

Need help axle identification, I'm trying to rebuild my Dana 44 front axle, truck is a 77 f150 I seem to have misplaced the axle tag... of course. So the numbers stamped on the axle tube are semi visible. What I have thus far is 603781. Cant quiet make out the last number, looks like a 9 but I am not sure.

What I am trying to figure out is what inner axle tube seal I need. Bronco Graveyard sells two and I'm not sure which I need.

The seal that is inside my differential looks like the one pictured here however the webpage says for years 78-79 and mine is a 77. Not to say the axle wasnt swapped.

any help would be much appreciated!

No such number, look at it again. It may be Dana ID # 603781-9 / Ford ID # D6TA-BAD

Dana 44-7F Front Driving Axle / 3.50-1 / Free Running Hubs / 3,500 lbs. axle capacity / Front axle parts list #30.4G

1976/77 F150 4WD Regular Cab.

D6TZ-1175-A .. Spindle Seal - Inner // 2 47/64" O.D. x 2 1/16" I.D. x 17/32" thick.

That's what I was saying I believe the number was 603781-9 I just wasnt sure about the 9. So then I assume that means that I need the seal part number 12199 the smaller diameter seal?

Read your post again, this is not what you said.
You said the number was 607831 w/a possible 9 at the end. I knew that the 3rd digit of 7 was wrong the second I read it!

I edited in the seal part number.
