Welcome.



Orion or Toyota split case...



You could go with a Toyota split case from an 1981 to 1987 40 or 60 series...you are going to need an adapter for this or an Orion. The Orion will get you a 4:1 low, which you probably will not need with a 700r, unless you are looking to get into some really tough trails....and even then, with 35", you probably will not need it, with the 3:1 first in the auto...


Good luck!

You certianly could go with a Dana 300, but you will need to build a new rear axle, as the 300's output is centered opposed to the offset output in the Toyota cases...


The Orion is a cast iron case made by Advance Adapters, that has a 4:1 low range gear set and supposedly is going to have a 3:1 gear set available for it in the next year. It is designed to be a direct replacement for the older one-piece tcase.


If you are going to build a new rear axle, then just make it a high pinion, and go Atlas!


Good luck!
