Who here knows a bunch about the NP205. I want to know if one could combine a divorced driver-side parts onto a married passenger side case and make it a divorced case. It appears that the divorced GM and Dodge cases are somewhat rare and cost way more than the married ones. It looks like one could put the input shaft/yoke and housing from the Ford case onto the Dodge/GM married case and voila divorced passenger side NP205. I know that there are different sizes of bearings and seals to contend with, so I may have to do my homework really well before I go shopping.[IMG]file:///C:/DOCUME%7E1/Owner/LOCALS%7E1/Temp/moz-screenshot-14.jpg[/IMG]

I ask this because I recently acquired a Dodge KP D60 and am tempted to keep it and run it in my '71 highboy with the D70 I also acquired. But the Dodge D60 backwards compared to the Ford, hence my weird question.

Please hold the purist reprimands, I am curious and just want to know.

 

I don't think it can be done. Two options I would suggest are: give me the 60 or look for a divorced Dodge, chevy, or international case. They shouldn't be too much money since those trucks are going to the scrapyard everyday now.

 

I cant answer this, but if you try it let us know how it works

 

Scott:

While I have to do a little more looking, I am very confident that you cant use dodge or chevy parts (external input) on a ford, nor can the opposite be done.
As I recal the bolt patterns are very different. One pattern used the "racetrack 8" pattern and the other used the "round 6". That will be a problem.
Married adapters are not interchangeable, and the two bolt patterns are entirely different. This changed after 85 I believe, but is only applicable to the married units.
This will not be helpful.
There were different input shaft options, and some of the smaller 10, 23, 27 male input shaft units used a small bearing, and if your case had a larger 32 spline input, it will use a larger bearing. Now that being said, the case can be machined from a smaller bearing to a larger one, but if it started life as a large bearing, you cant put the material back to accept the smaller bearing required for the smaller male input.

Now, lets think about this. I think it might be possible to use the ford input (31 spline male) in the dodge or chevy case, but you will have to use the seal and bearing retainer from the dodge so it will bolt up. The ford used the larger bearing since the small input was never used in fords at all, and I believe the OD of the bearing is larger than the ones used for the dodge or chevy, and you will have to modify the case to accept this. This is reasonable, but will require a complete dis-assembly. Some modification to the retainer will probably have to be performed, and there might have to be some time spent obtaining a seal, but still I believe this would be the easy part.
I am looking around to see if the input shaft actually contacts the internals in the same fashion, and with the same depth for all 205's, ,and I do not see any variation here.
Might have to look at the cost to obtain all of the parts, and actually complete this upgrade VS the potentially higher cost of the slightly more rare case.

Here man, I just found this while looking through some of my pics in my documents.
This should help explain without having to type using my primative typing skills, or my rusty old memory.

Good stuff, and Good luck.

Thank you Ed.

I actually read through that site last night, it has a ton of valuable information on it. I was just trying to kill my curiousity, and this is the place to ask.

 

You could always sell the dodge D60 and get a ford one.....Just a thought. That will save you a lot of troubles IMO.

 

I would prefer to use the Ford side D60, but the Ford models are much more expensive and I have not seen any for sale in my area. It is just the cost factor, but maybe I just need to be patient and wait it out. Time is on my side as I am a non-traditional student until next December. Then the money will be thicker and more consistent and time should be easier to come by.

 

like i said just some food for thought. I got my D60 with the matching rear for $400.00. deals are out there you just gotta dig. I think he stole the truck and was urgent to get rid of it though LOL. (just kidding I don't really think that)

 

Ya, I know about the deals thing. It is just a matter of being in the right place at the right time and having the money to play. Sometimes I have a couple those things line up but not all of them. Funny how that happens. I have turned down two Warn 8274 over the years for that reason. I wish I had made it happen now.

 

It happens to the best of us I steal money out of my 401k anytime I come across something too good to pass up. I figure I am young yet, I'll worry about retirement money later LOL. Don't let my financial advisor(aka my old lady) read this.

 

I don't have enough in my 401K to do that yet. I just started mine last summer. I have never had a job that contributed before. It is kind of a bummer to be starting at 30yrs of age.

 

I started at 21 So I have a decent jump on it. At least that's what they tell me. I wouldn't know the difference either way LOL.

 

Hey I did some searching and I knew I've seen this somewhere. The guys name is Tude on here you can do some searching for more pics. I know it can be done I've seen it in person but only with a chevy diff. This one is defenetely a dodge with selectro hubs. hope this helps

 

I found this in on a thread I started called Post a pic of your 4x4 in the 73-79 forum. It's on page 19

 

[quote=73 ford guy;6138345] I knew that somewhere there was a some redneck that had done it.......

The cases seem to be rather difficult to find.

I thin I am going to sell my D60 to my buddy Ted for his new '68 four door Dodge project and wait till I find a Ford D60 front. I think it would be easier and keep the headaches smaller.

I need to light a fire under my rear and study for finals so I should go.
