My truck is automatic and has Dana 44 with 3.07 gears in the front.

You may have it backwards. Some 3/4 ton diff had 10 bolts and the FF had 14.
Later than 67-72, S/15s had 10 bolt diffs, but that was coincidental and another type.
The 12-Bolt Truck rearend was different from the 12-Bolt Car diff, too.
I'm not expert on the EATON and HO52 rears. They were 3/4 ton iirc.
