Typically the best route to have a 4x4 truck is to get one that is already built from the factory the effort to convert is usually to great to do but how about the non existent versions. like a short box supercab in the 73-79 flavor for example, or even a extremely rare 73-79 longbox crewcab 4x4, then the conversion becomes worthwhile to do there is about as many ways to convert a truck to a 4wd as there is people willing to do the conversion below is one method on this conversion if you decide to convert yours may vary here is some pictures of a buddys CrewCab that we converted from 2wd to 4wd this truck has the narrow 34" wide frame it is a F350 and it is a good frame only problem its 2wd the 4wd section is from a F250 1979 4x4 has the new style steering and overall the best design for the 250 and 350 4x4 the 79 F350 4x4 shares the same frame as the 1977.5-1979 F250 4x4 thus pretty easy to find We started with a pretty solid 1 ton 2wd Long box CrewCab has a few dents but no rust and in pretty good shape over all ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() A 2 post lift is real handy in a conversion like this ![]() ![]() ![]() ![]() The Donor Section from a 1979 F250 4x4 standard cab truck ![]() the original 2wd front section cut from the truck frame ![]() ![]() ![]() Started the welding process the truck is now has a 4x4 chassis ![]() ![]() used my frame perches to install the 460 in his crew cab Link to the perches 460 Frame Perches ![]() ![]() ![]() ![]() ![]() Everything Just fits when done correctly and with correct parts ![]() ![]() ![]() ![]() ![]() Drove out under its own power until we can back to it to finish the truck ![]() ![]() He has a Dana 60 Front Axle that we rebuilt to put under the truck this will compliment the Dana 70 rear axle nicely. Until then this old 1/2 ton axle works to let the truck move in and out of the shop ![]() little clean up still to go until it is done ![]() Current status of this truck is the Dana 60 is in and the truck is being driven things to be done yet 1. Rear axle ratio change from 3.73 to 3.54 2. Front driveline installed 3. Body work and paint 4. a lift is slated to be installed at a later date |

I did a convertion of my first crewcab that I built. I started with a 1974 f250 2wd longbed. I mounted a duivorced NP 205 transfercase in the exact middle. By doing this my front and rear drive shaft was interchangeable and I carried one spare at all times. Then I mounted a 78/79 high pinion 60 in the front. I built my own front crossmember with the correct spring mount width. Then I just cot a hole in the frame just like original for the shackle mounts on the rear. It was actually fairly easy. I wish I never would have sold it. My new project is a 1977 F350 4x4 shortbed. It has a front axle like I have never seen before. |

Dana 60 low pinion(regular) with disc brakes and open knuckle? one application only if it is......ok 76 and 77 crewcab f250 4x4s. that is a rare beast |

kicker is though F350 4x4 first year was 1979 the dana 60 in the front should up as early as 1975 but only in crewcabs F350 was never made as a shortbed truck in 4x4 form for sure and I doubt it made it in 2wd form either |
