Re: 203 conversion

You don't need any except the kit. Just google np203 part time kit, that'll bring it up. I like the 203, just more versatile, but the 205 is supposedly bullet proof, so it's up to you.

Re: 203 conversion

It's a pretty easy conversion and well worth the time, effort, and expense.

All of the ones I have installed have good, well illustrated, directions.
Depending upon which hub you have on the inside, you may need a "pin punch" to disassemble it. IIRC it's 1/8"? That is somewhat of a special thing that might slow down someone who is not expecting it.
Some of the them are a simple bolt-together thing, others have roll pins holding the "cross" in the hub. There really is no way to tell which you have until it is opened up.
I have heard people say that it is the 3/4 ton trucks that have the heavier (bolt together) unit, but I have seen them both ways....

Bad planning on your part does not necessarily constitute an instant emergency on my part....

The great thing about being a pessimist is that you are either pleasantly surprised or right.

Were it mine, I would pull the range box off the 203 and mothball it, swap it out for a 205 and use the rest for a boat anchor...but it all depends on how rough you are on things.
