Ductape,

The NP203 is full time but can be converted to part time. It is a 2-section transfer case, one section for the range box (low gear) and one section for the f/r driveline split. The 2 sections of the t-case can be separated and used independently. It is common for rock crawlers to yank the range box section from an NP203 to use a 'doubler' in their drivetrain, since the 203 has a 2:1 low range. The NP203 and NP205 were made in the 70's and both have heavy duty iron cases and can handle quite a bit of torque output from the engine. The 205 is an all-gear part time t-case. The 203 uses chain drive with a center differential for full-time operation.

You sound like you know about transfer cases a lot. What do you know about the NP-24? Thanks

Sorry, I don't know anything about the NP24.

To OP....we have a semi truck trailer at work...it is 40 feet long...it has 2 sets of duels on real of trailer...they instaled a tag axle kit to the rear (that looks like it came in a complete kit)that is single wheel ( like a dump truck tag )that is air powered and ride...if you had something like that on the very rear...if in the up position?..your truck would drive as original...but soon as you drop the fifth wheel on?...hit the air switch and drop the rear tag ..this would be easy and way cool?...just my 2

Put super singles for the rear instead of duals.

Yes that was me. I took a trip by myself to New Orleans. Then Myrtle Beech. Then back to PA. Nex time. Say hello.

Clearly COST is no problem, I love it by the way. What ever you do, IMO, you have to leave the "sport" stickers on the flairs. They are a nice touch, and who would have guessed the mud flap design...lol

Looks nice, very nice body work there on those fenders.

Did you get the second rear axle from a cab/chassis truck? It looks narrower than the original rear axle.

Not sure what the rear came out of. But you got good eye. It is four inches shorter. But I got 2 inch spacers on each side to correct this.
