If you can find one 97 F250, not a super duty more like a heavy 1/2 ton, used the same body as the f150 but the heavier trany and axels under. prior to that apx 97 date ford called them a 5/8 or heavy 1/2 ton. still a torsion bar front end. like some else mentioned floor shift for 4x4 or dash dial some were a manual linkage. I have 99 f350 v10 manual 4x4 manual hubs solid truck but hell on fuel. I have had 6.9 and 7.3 ford Diesels. 6.9 was an 85 f350 work truck plow truck sent it down the rd. in 06 frame was giving up, body long gone. 6.9 was about the last of the non-emmsion units. 3 headaches with the 7.3 ( still a good rig though) is the turbo and the wiring for the injectors is placed in the head gasket, yep oil pan rot inside to outside. the 2, 6 liter desiels after the 7.3 i would not bother with. Although the guys over on the desiel forum have worked out most of the bugs. most of the problems caused by emission control garbage, that and the proverbial asian supplied electronic parts failure ( not limited to ford - across the board)
Mine is a 2000 with 108K mikes..I have had no issue with the wiring yet...
I have replaced the engine oil cooler, it rotted from salt..I replaced all the brake lines..I replaced the hydro-boost (power steering) lines...wheel bearings (F550 diesel 4x4 with a 9' plow)..front drive shaft CV joint (WTF!?) and U-joints...fuel pump...transmission because of the leaky seal...rear main seal on the engine (because I could when the trans was replaced)..and I replaced the GPR with a top quality unit- and wired it direct to a switch on the dash. No more 7 second GP cycles (not enough in cold weather) and no wasted GP cycles (The GPR comes on every time you turn the key as stock, wears them out prematurely). Now I can start it @ -10F with just the glow plugs. I hold the switch for 45 seconds to a full minute, and bang!
I will need to replace the oil pan soon, and when I have that done I will also send the cab to my friends shop for a complete facelift- new corners, rockers, paint, the works..and new fenders too when it goes back together. I have run the numbers a dozen times: It's far more cost effective for me to fix the one I own outright than buy a new one. Even if I spend $10K doing it. And the frosting on this cake is that I prefer the style and interior of the 2000 over the hideous new Super Duty.
