exactly as title.  rear bronco 9" is 65" and front44 from f250 is setup for leaf springs but states it is 63.25.  would this be too gooofy or stout to run as full widths in a YJ.  i know to match wheel pattern u can swap out the hubs from the bronco to change the f250 to match.  or should a guy just stick with the f250 diffs. which woukd be the hp44 and rear 60.  ideas?

Usually as long as the widths are within a couple of inches you won't notice the difference. Hp44 is pretty tough, 9" is tough and aftermarket support is huge. Rear 60 is tough too and common. I have one if you want to have a look at it, under a yj frame too.
The swap is pretty common, d44, 9", d60, 14 bolt, all common swaps for yj's.

i have access to both rigs back home in thunder bay. so trying to determine the best route to go.  my budd has a pile of 78-79 fords 250/350 and broncos.  however all the front 60's he has sold except one spare he wont sell lol.   but will give me whatever others out of em that i want.  so I was leaning towardsthe 44/9" combo since i have brand new 5.13/5.14 gears for them.  but i would need help with the swap.  I would love to learn how to do it and willing to pay to get it doneproperly.  but would really liketo help out.  I am a welderby trade but never done a lot of vehicle work. been trying to learn on my own and with good advice fromsome peopleon here too I have been slowly pluggin away learning all i can about this YJ!  Great feeling to be able to fix something or build it on your own.

Go with the rear 60. The pinion is to low witha stock nine, and the casings are prone to breaking in half, and the housing warp to easily.

The front 44 limits you to a 37 if you like throttle.

Those are 14" Kings, they are worth more than the rest of the Jeep.
And that suspension was a P.I.T.A to build.
That being said, it's freaking fantasic  ;D

I got a 79 f250 D44 in the front of the YJ. Spring under on 38'S. When it was open I never broke a thing. And I likey the go pedal! After I locked and and put in shafts, hub are the only thing I break.  But only if get wedged in somewhere. 

My springs are tweaked out a little but nothing I have ever worried about.  Steering was super easy to hook up as the passenger knuckle doesn't need much work to make it flat. I used a big file!
