Hi.

I'm looking for a Montero, but I've never owned one, so my learning curve is pretty steep right now. I've been reading everything I can, and I'm sure the answers to my questions are out there somewhere, but I'm having trouble finding a few specifics.

My local wrecking yard has a '95 SR. The air pump was missing, but I grabbed the rear locker. They also have a 3.5 Sport, and I grabbed the 4.90's, which means I now have a pile of gears and axle parts for a vehicle I don't even own. I have a feeling this new addiction is going to get bad. Anyway...

I've read that the ideal vehicle is a '95 SR because it has a center locking diff, which I therefore assume the others do not. Is this something that can be swapped if I grab the t-case, or is it dependent on a bunch of sensors and wiring? There seemed to be multiple air lines running from the spot in the SR where the air pump used to be. Is the center locking diff actuated by the pump? Is there anything else actuated by the pump, or just the rear lock?

Also, a couple of the vehicles I'm looking at have the 5 speed trans. Do the 5 speed vehicles have the same Super Select 4wd system, or something different? Every reference I've seen is in relation to the automatic transmission.

Any input appreciated.
Thanks
