I looking for any information about swapping a 2wd body on to 4wd frame. I have a 1986 2wd truck that the body is in great shape but the engine is in need of repair and a 4wd 1986 that the body is rough but has a new crate motor that runs great. I am not sure if it would be easier to replace the engine or swap the body. It would be nice to have the 4wd system but I have not did an off frame project before. I am a rookie wrench that can get the job done when needed. My first concern is the cab of the 2wd fitting on the 4wd frame due to the transfer case. They are both the same year...long bed trucks and would make a great truck once joined together as one.

You should be good to go. Cut away for the shift lever and go for it.

In talking with some mechanics they stated that I would need to change the transmission tunnel in the cab to make this work due to the 2wd drive does not allow for the tranfers case. Is this correct???

The cabs should be the same for both. KB
['86 2wd cab to 4wd frame swap]
I did the earlier generation: a '8x 2wd cab onto a '78 4wd frame. In my case I had the choice of lifting the cab (Ewwww) or cutting out the driveline hump from the 2wd and bolting in the lifted hump from the 4wd cab. I did the latter with no problems, and very few saw blades. A good torch and a steady hand might go quicker, I dunno.
Once old cab is off, check the mounts, eh? Being cheap I welded in the biggest galvanised washers I could get and didn't replace mounts.
Yeah they don't restamp the cab shapes for 4x4 or 4x2. It should be the same.

It's not actually that much different - the center of the floorpan from a
*manual* shift 2wd will fit a 4x4 with no modifications. The *automatic* 2wd will need to have the floorpan worked on a bit - I've got this conversion waiting for me at my father's house, as the cab on my '79 4x4 is completely shot (see: rustholes around windshield) and I was given a 2wd cab from a '78 Texas truck that's almost mint - even still has carpet in pretty good shape.HTH

Nope.
Good luck, enjoy, and keep a sawz-all handy.
Is the" hump" area a bolt in like the older fords or is it a complete molded steel floorpan ?
Thanks I have been watching this thread, I may do the same if I can come up with a shortbed 4x4
Have a look and see.
