All D44s are 10 bolt. Isuzu only used them in the rear so would be tough to make them work right. You can flip them for a high pinion and make the gears turn right but then you have oiling issues for the pinion bearing.
Side note, when I was at the pull n pay this weekend ALL the isuzu D44s were torn apart and the r&p gears gone. Jeep guys like to use them.
Instead of a hybrid 12bolt/d60, if I wanted to spend big money, I would go with some Atomic Axles..
