what gears are these???11 9 66 dana 18679 a309 50-11 they came out of a 67 gmc w/cup and ball front axle, also would a 14 bolt be factory in this truck also? it looks just like my other 3 just has smaller drums and the pads are spaced out further.

50/11= 4.54545454545

4.56 sounds about right.

I thought the eatons came in those, but somebody could have swapped it in. Sounds like a close knuckle front...not real desireable axle.

A '67 GMC 3/4 ton would have either the Eaton or Dana 60 rear diff.
