Do you want a high or low pinion?
My understanding (after being ripped a new on on pirate) is you can't get a full sized Ford low pinion D44.
I had never seen a low pinion, full width 44 in a Ford either.....until last weekend at the junkyard. It was in a early to mid 70's Econoline van that had a Bronco style C4 & D20 transfer. It was really a wierd combo of parts, but it looked close enough to factory that I don't think it was home built. Was there a "Quigley" type company making factory style 4wd vans in the 70's?
Not only was it full width....or damn close, definitely wider than Early Bronco.....it was also 8 lug on drums, open knuckle. No leaf springs in front, it had Bronco style radius arms and springs. I went back to snag the trans and transfer case, but someone beat me to it. It was gone, but the front axle was there as of last Saturday.
Oh yeah....it had twin sticks on the 20 also....but those looked kinda home built.
