There's a place in Sandy Eggo that sells XLs on eBay a lot, I think under the name etires.
The NP200 t'case doesn't like speeds much over 55. It's an overheating problem with them. Freeway speeds for extended periods (like much more than 20 minutes!) will usually result in a way-too-hot t'case probably ruining the seals.
Best bet is to get ahold of a divorced NP205 and swap that in instead.

thanks glad to be here.
Strength wise, the 200 is a great t-case. Sustained drive shaft rpm of 2500 or more will get it hot. Like 280 degree plus case temps. With stock gears and Michelin tires, that means about 54 mph. Short bust of what ever you can do are ok, but not long speed runs.
Remember if you didn't build it you can't call it yours.

I think the low gears with the large tires coupled with the OD transmission will definitely have the NP200 screaming (literally) for mercy. Just get a 4WD NV4500 and a NP205 or use a 2WD NV4500 with a divorced NP205. If you are modifying the truck to that extent, there really isn't much point in keeping an inferior transfer case when 205s really aren't that expensive.

Are there any specifics on a divorced NP 205 that I need to know before buying one? Any year? Any model truck? I appreciate any input.

Barrman, my truck runs pretty well now, but I can not imagine sustained speeds of over 50 with it. I am planning on taking some long rides with it of about of 40 to 60 miles at 45 MPH, will I be OK with the stock drive train?
Dodge, IH, GM and Ford all used the np205. The Ford version was driver side drop and not what you want. The IH and Dodge version was 31 or 32 spline (I always forget this number) The GM version was 10 spline just like the NP200.
More splines in theory is stronger. But, being able to transfer the yokes from the 200 to the 205 sure does make the change over easier, faster and cheaper. It also make the stock e-brake going on the 205 an almost no brainer. (The brake braket from the 200 needs to be machined a little to fit the 205.)
I have a fine spline and am having trouble finding the proper yokes for the 205 to fit the stock u-joints. So, I don't have it installed in my truck yet. I would like to swap my 205 for a course spline unit as a matter of fact.
That is the main difference in a few words.

thanks Barrman. That helps a lot. Trying to get a parts list and a project goal budget.

Don't forget about a np202 either. They can be found in IH trucks one ton and larger. They are very similiar to a 205. I am using one in my truck. Was pretty easy to install it with the 200 ebrake band into my truck. The shifters took some moding but they are in the stock location.
