Can someone please enlighten me on which years and models had divorced and non divorced np 205's. And which years did they do 203's vs 205's? I have a 78 F250 (back home so I cant go crawl under it) but im looking for a non divorced np 205.

Thanks!

 

73 - early 77 had divorced transfer cases in the F250's. Not sure about the lowboy's made in those years. Late 77-79 had married in the F250's. Always married in the F100-F150. Not sure about 203 or 205. I think it is random. My 78 F150 had a 203. My other 78 F250's have 205's.

 

Someone correct me if im wrong but I think what I found out is the 203 is the full time 4wd and the 205 is regular 2wd/4wd.

 

You are correct.

 

How much are they worth?

 

Not much, Everyone usually wants the 205. Unless some is doing a doubler, most just swap them out.

 

yeah Im putting a doubler in my cj behind an ls 6.0 thats why im so curious haha. What is needed to bolt the 203 to the 205? Any adapters? Or is it a bolt on?

 

Not sure. Hopefully someone with more knowledge will come by and help you out.

 

Yeah, Id imagine there's an adapter and stub shaft but thanks for your help!

 

My 78 f250 had a full time 203 that was converted to part time.

 

On a doubler only the low range part of the 203 is used. couple outfits make doubler kits.
Going into a CJ? keep in mind the length of the drivetrain. Its been done but makes for a short rear drive line unless you have allot of lift.
Is that going to be a ford 6.0 or a GM 6.0?
If Gm you will need a gm 203 and the correct adapter to go with what ever tranny you use.
For a Ford 6.0 your going to need ti find an adapter to bolt up a 203 to what ever tranny the power stroak has...that could be tricky. Ford dropped the 203 and the 205 in 79.

 

Off-Road Design makes a kit and I think Northwest Fab makes one. Save some pennies though!

 

Yeah i was looking at the Offroad Design. Its a chevy ls 6.0 but the jeep is being comp cut and the axle slid back and front forwards with 3 and 4 links. But its still a long setup... But $1000 is cheaper then $3000 for an atlas and adapters!!

 

I also have a '78 F250 with no locking hubs so i always thought it was full time. But i can put it in 4x4 in the cab and thats when it locks in.....i would like if someone would explain which t-case i have and how it works? Thanks

 

Also guys, what are dana 70s worth? I am using the 60 front but a 14 bolt rear. Someone wants my 70 but I have no idea what they are worth? Its complete.
