cool, what kind of adapter did you use to hook the tranny to the 203 range box. Or does ORD make an adapter that i will get when I purchase the doubler kit?

I think you can just redril the face of the 203 then use the t400 input gear which is a 32 spine. You can also use the Advance adapter plate and the dodge tailshaft housing for the 4500.

Tim (tlarsw) is running the Doubler using the NV4500. Check out pics on his site.

The best way to bolt the 203 to the NV4500 at this point is to use the 32 spline input in the 203 and re-drill the face of the 203 gearbox to the round pattern that's on the back of the factory NV4500 GM 4wd adapter housing, then you can bolt them right up. One hole causes problems due to being near the edge of the casting but it's easy enough to move a little and make it work.
Once the 203's bolted up you just do the Doubler like any other system and you're done.

Stephen:
What about us Dodge guys? I've got a '95 Dodge NV4500 and a '75 Dodge NP203. I think they're both 23 spline. Will the redrill trick work for my setup?

And if it will, is it an impossible task for the home shop? I guess there must be some pretty close tolerances as far as getting the two pieces centered correctly.

For the Dodge, if they're both 23 spl. you just need to check the stickout length and you should be able to re-drill. The beauty of this is the bearing retainer on the 203 is identical or very close to what needs to fit into the 4500 adapter, so it indexes the shafts and the bolts just hold it together and set the rotation.
