What would you suggest as far as parts that you can bolt in for a 2wd to a 4wd conversion to a 84 Ford F-150 with an i6 engine and 3 speed + granny gear transmission? I need more details as far as what front end I need, what transfer case I need and what rear driveshaft I need? Thanks!
You'll also need a 4x4 transmission, transmission crossmember, and transfer case. I'd try to get one that matches your transmission. NP435 with a SBF bellhousing pattern (300, 302, or 351w). With the 4x4 transmission, you can put in whatever transfercase you want behind it. the BW1356 is going to be stronger than the NP208 for the chain drive cases. The NP205 will be even stronger than that, but the low range won't be quite as low. I'd probably just use whatever transfercase is attached to the NP435 that you pick up. That will ensure all the shifter linkage is the right length and all. Grab the front driveshaft from that same truck as well. The rear driveshaft will all depend on what cab/bed configuration your truck is. If you get lucky, and the donor truck is the same as yours, grab the rear driveshaft too. Otherwise, just find a driveline shop, and they can make you a new one.
But, outside of that, you can honestly use whatever transmission/transfercase combination you want. These trucks are all fairly universal with parts swapping from 1980-1996. There are some oddball parts, here and there, but with a little extra work, you can swap in whatever you want.
Having said all that.... If I were to start over and do it all again (which I actually did), I would do a straight axle swap at the same time. Its not much more work, you can damn near piece together a bolt in kit with the right parts selection, and it'll be a good upgrade.

Do you have an automatic or manual transmission? If its auto like mine is, then i think your doomed like me. There are no automatic 4x4 transmissions for the 6 cylinder, only manual (which means you would also have to convert to a manual transmission) and i dont think that you can bolt up a 302 transmission to a 300.
can anyone confirm that what im saying is correct, or can you do this tranny swap?

Ok cause I have a 300 a 351w and a 302 and have done swaps and had to get a whole new bell bousing for the 300 cause the 302/351 would not bolt up unless a modification was made

I was thinking about doing the same with my 95 F150 that has a rusty frame but I noticed all with 4 wheel drive have the large trans hump so that might be a issue if the truck that is going to be converted does not.

I'm seriously considering doing this, would i need to do anything with the wiring? Also would the steering be an issue or not? Another thing, does the 4x4 tranny and t case have to come off the same engine as what u have or do they all mate up the same? And lastly my truck has all new front springs shocks and calipers, can they swap over to the 4x4 axle? Thanks
