nv4500 or 700r4?

There are several different passenger side drop divorce mount NP205s. Chevy, Dodge, and even some larger International trucks had them IIRC. Ford made them too, just the wrong drop for what you'd need.

However, running a divorced t-case would be my last resort. Especially since it's not hard to run a 205 behind an NV4500 or a 700R4.

When did chevy use a divorced np 205 ? Never seen one factory installed . I know they used a divorced rockwell t case in the sixtys.

just tagging along here, i'm pretty sure my 65 Chevy 1/2 to 4x has a divorced 205. I cant check for sure because it's 40 miles away..

I have a 1966 chevy 4x4 that has a rockwell t case - it has a 1.94 low range and looks similar to a np 205. Take a look next time you are under your 65 - i would realy like to know

 

[4bogginchevys]

will do, I cant be sure because I havent been under it in well over a year

 

[4bogginchevys]

just curious if someone knows off hand, what was the first year GM offered the 205?

The 66 will have a Rockwell T-221. 68 or 69 was the first year for the 205 case in the GM 4x4s.

Did they ever use the NP200? Almost identical to the 205 and just as strong, if not, stronger. I think it had a big goofy parking brake drum on the rear output.

Kid, didn't you have a 700r4 for a while before you got the cummins? My only holdup now is the adapter for the 205 to the 700r4. I can buy different output shaft from odff-road design but i don't know what to use to physically BOLT the two together. Do you know??

 

[Recovry4x4]

NP200 was not used in the GM 4x4s. Mr Brown, the adapter you need is a GM part used in the 68 to 73 trucks that mated a 350 turbo to the 205 case. It has the same bolt pattern as the 700R4. I don't recall if you had to massage a seal surface or not but that is the adapter you need. Used to be plentiful but not anymore. Usually they have one of the mount ears broken off.

 

[mtjbrown]

Thanks much for that. The guy at off-road design said they might couple of those laying around. I'll check it out!!

If I'm not mistaken, even with trimming the output shaft you need an extra 2" spacer to make everything bolt together.
