I have got a 92 4 door longbed standard shift F350 which I would like to look into converting to 4WD, dually as well. Im willing to go through the effort instead of just buying one, since it was my first truck and its been in my family since it was new. The dually conversion shouldnt be that hard, but im wondering how hard the 4X4 conversion would be.
gonna avoid the spacer method on dualing it up since I would like to throw out my rear axle and go from single rear wheel and 355 ratio to dual rear wheel and 410 in one shot. Thanks.

 

find a donor truck, and just take measurments. i have done 3 of them so far. last one took me a weekend to swap.

 

Cool. Someone told me that i couldnt use my same transmission, is that true?

 

you still can if you use a divorced transfer case. if you want a 4wd tranny with a direct bolt on transfer case, youd need a new tranny/x-fer but if you run a divorced t case, you would just need some driveline mods

 

You can keep your transmission even with a married transfer case, just change out the output shaft. UNLESS you have the parking brake on the transmission, in that case you can remove the parking brake, put the extension housing on, and bolt up the transfer case.

 

its a standard shift so i shouldnt have any trouble with the parking brake now its just a matter of finding a donor truck...

 

try to find a kingpin dana 60 for the front. gona cost a little more but worth it.

found in 87-94 f350's

 

So, since this isn't a totally retarded idea, what parts will I need to 4WD my 88 F-250 5 speed?

 

front suspension, hangers, shock mounts, brake line mounts, transfer case driveshafts, rear factory blocks, plus a tape measure, air hammer/grinder, and a marker.
