Well,,,,,,,,,,much depends upon which D44 front axle you select, and you might give up the idea of the rear D60.
Your Bronco has an axle that shares the same axle strength as the D60 rear. So other than weight capacity, the rear axle swap would be nothing more than,,,,,,,,,,,,,well there is not much of an advantage.

For the front, if you plan on running leaf springs, then you have your work cut out for you. This frame has no provisions for this, so you will have to be pretty sharp with a tape measure to verify "square".

Coils are pretty easy to keep.

Lets hear what you really want to do with this ride, and then you can recieve some feedback.

well my intentions with the bronco are to lift it and use it as a mud truck slash rock crawler nothing huge i just want a big off road truck that i can still drive to work the odd day . so i should stay with my 8.8 in the back? the front diff is out of a 79 f250 with leafs and all mounts and steering links.

ok, know that the D44 steering is much different than the steering on your bronco. The bronco is not capable of using the early push pull style steering, and should you decide to use front leafs, you will run into problems converting the inverted T style steering. Clearances between the drag link and the pass side spring will be tight.
Making spring perches will not be that difficult but the frame widths are different so you will have to make spring perches and hangers for your bronco. This is much easier to install coil springs like a 1/2 ton truck or bronco from the 78/79 era.
With the 35" tires, it is possible to make the 44 and rear 60 survive. This is a very reasonable swap, you just have to have a plan on what you want to do.
