Ford was very smart with there t case setups. All t case's use the 6 bolt round pattern, and with the right depth adapter anything should work with anything. This only counts towards the older stuff, 96 and older.

The reason I am asking is because my 83F250 has the NP435/BW1345 And I Am wanting to change the 45 for the 1356.

The case will bolt up no problem. The 1356 was the replacement for the 1345. Whether or not the cases are the same legnth or not I don't know. That would be the difference between driveshaft mods or not.

Search the junkyards as some of the 1356's came with a fixed yoke. Really all it is is a different tail housing and different output shaft, all of which can be obtained if you really want to swap it out. But junkyarding may be your best option to find what you need.

well, with the slip yoke, if your DS breaks, then guess what, the shaft slips out and you puke fluid out. with the fixed yoke, it your DS breaks, it just keeps spinning away throwing what's left of your shaft into the bottom of your truck until you stop and put it in neutral/park. It all depends on what you are doing with it (street driver, dedicated trail truck, mall crawler, import crusher????)

You'll be fine then with either. If you already have a DS made up for the fixed yoke, then look for that case, usually found in Broncos. If you have the slip yoke, then look at all the rest of the F-series trucks. Just be careful about the manual shift vs. the electronic shift. You can go to manual fairly easy, it's hard to convert a manual truck to ESOF without spending a pretty penny on the wiring.
