Divorce-mount np205
I\'m thinking a divorce-mount t-case would be better, so I want to run it by the masses. Setting it up doesn\'t seem too hard. The 1.96:1 is fine for me as well, but I\'m not sure about the durability of the case itself. Also, did any drivers-side drop divorce mount 205 come with 32 spline shafts front and rear? If not, can they be retrofitted? And finally, can they accept a 1410 u-joint? I hope it works, because I won\'t have to mess with the transmission that way.

a ford divorced 205 is 32 spline on all the yokes and is driver drop, yes you can get 1410 for it and you can't get any stronger of a case, those things are one heavy sob piece of iron.

that is the case i am running in my wheeler, pretty hard to break them

What he said.

As far as a light truck mass produced transfer case, I don't think there's anything stronger than a 205. Ford and GM used them in 2-1/2 ton trucks for quite a while (i.e. 4wd F600s and C60s in the '70s and '80s).

RE: Divorce-mount np205
Cool, thanks guys. I found this one locally. Do ALL divorce-mount ford np205's have 32 spline yokes/shafts? [Image: gallery1]

Also Ken, do you have any pics of how yours is mounted up? I will keep searching, but I'm having a hard time finding a custom mount idea.

Well, the guy thinks the running gear is from a '77 ford, so it looks like this has the 32-spline shafts. Yay for me. Hopefully I can go this weekend and pick it up. Plans are to rebuild and inspect it within the next couple of weeks. Once I get a mount made, I will probably take the old shaft from the automatic and have one end shortened down to make the intermediate shaft. It's just sitting in the garage, since I used the shaft from the donor truck for the 5-sp. swap. Plus the other shaft has yokes for 1410's. The only other question I have is, since this truck has a carrier bearing, will I need to keep that with the transfer case setup plans? Or can I ditch it and put the output yoke of the t-case in the exact same spot as the carrier bearing? So that, basically, everything from the carrier-bearing back will be the same. Thoughts???

RE: Divorce-mount np205
all ford divorced 205s are 32 spline, yes you can put the case output in place of the center bearing, that would work just fine.

i have pictures on my other computer, i may have them also on photobucket, i have to look

here is what i did , it allowed me to bolt to the side and bottom of the frame and be able to run my exhaust, the pass side is pretty much the same, i had to box the end to allow me to adjust the height of the pass side since it is offset

RE: Divorce-mount np205
Yeah, you can do away with the carrier bearing. Only thing I'd be worried about is, at that point, the length of the front shaft. That sucker's liable to be pretty long and given the Dodge D60 up front is a low pinion unit, you might have to worry about dragging that thing across some stuff if you ever wheel it.

a long front shaft is not any different than any of the ford highboy trucks, the long shaft would also help keep decent driveline angles with using a low pinion.

RE: Divorce-mount np205
Thanks guys. Really makes the decision that much easier. Also if I decide to swap in a bit heavier-duty transmission (and one that parts are more readily available for), it will simply be a matter of transmission mount fabrication. Being as how it has a pilot shaft, do I have to be dead on the money when lining the t-case up to the output of the transmission? Last question, since the t-case uses the yoke-style front output, can I just have a single u-joint on each end, instead of the double cardan style that comes factory on the dodges?

Driveline angles would be really helpful, as I'm thinking a bit more lift than I originally anticipated. If I can get them equal-length, that would be sweet. Also, thanks for posting the pics Ken. Those yellow bushings on the pic I posted, I assume those go to the original highboy cab crossmember? So in essence, I really could build a crossmember with a slight hump and re-use those brackets/bushings, right? Actually, one more question. Should I get the new driveshafts with slip splines (or whatever they're called) built into them? Basically taking the slip from the yokes to the driveshafts. I'm sure my driveline guy would need to know that.

yes on the single cardan slip shafts, the factory ford mount i believe was a big crossmember with a hump in it so i guess you can make something like that.

your output of the trans does not need to be exact to the t-case input, ujoints can handle angle but to have the least chance of vibration you want it to be as straight as possible, mine is actually offset and i have no vibration and i built my own shafts.

[Image: morestuff022.jpg]
its about a 8" shaft and 2" offset

RE: Divorce-mount np205
Yeah, keep the output shaft of the transmission and the input shaft of the t-case as close to the same plane as possible to minimize chances of driveline vibration.

Jason, could you speculate where the t-case would be mounted and get an idea of how long each shaft would be based upon that? Just curious.
