Putting a bronco Dana 20 into '72 cj5.

Hi. I just joined this forum and have a couple questions reguarding my cj5. I just picked up a np435 and bronco dana 20 for $175. Both in perfect working order and I was wondering if it is worth the effort to use that t/c instead of swapping gears into my dana 20 and buying the adapter for the jeep t/c to np435. I am wanting to stretch her out a little bit without comp cutting or linking it...prob 2-3 inches in front and 2-3 inches in rear. I will be swapping axles when I start the build and thought about using the ford t/c and getting a front axles from a grand wagoneer since they are driver drop. Any thoughts or has anybody done this? Thanks alot.
