1985 Ford F250 4x4 6.9 Diesel 3spd Auto Long bed Regular cab.
Included are some pictures (hopefully) of my OD unit I pulled from a Van. I want to install this on the back of my Transfercase which is an NP208. I have a 3 spd C6 transmission and 3.55 gears.






Where I need help:
well, I don't know where to get the adapter to bolt this onto my transfer case. I dont even know anything about it. I emailed US Gear with no response.

I can't remember, but I think the OD switch said "DN2" or "DR2"
I can't find any part plates for this. No names on the OD.

Please help me find any information on how I can make this work on my truck. I scored a running remanufactured 6.9 Diesel with 10,000 miles on it, bolted to a C6 tranny that is bolted to an OD.
I got this all for $400.

 

I think the company that made that was bought out by Gear Vendors.

May try Advance Adapters at www.advanceadapters.com

 

I believe that is one of the old Doug Nash units. They have not been in production for a lot of years.

Good luck finding parts

I don't think they are built heavy enough for a truck, especially if you do any towing.

 

Doug Nash....I was trying to remember that a short while ago.

 

im sure it's somewhat heavy. it was from a one ton van that must have weighed 7000 or more pounds.

 

That looks alot like a OD unit that a guy I know but haven't seen in a awhile has on a 400 turbo chevy trans in a chevy truck that has an old B series Cummins that came out of a yarddog. If it is then it is probably pretty tough. His motor was making alot of power and I never heard him say he ever had troubles with the OD unit. He did out of the 400 Turbo transmissions. He would get it about once a year. I know it has been in there for awhile also. Well he pulled a 5.7 diesel out of the truck and put this motor in it.

 

U S Gear. looks old but still functional. they bought out doug nash. Should be all gear and very tough. contact them for more info.
