Count the bolts on the rear output . 7 bolts for gear drive, 5 for chain. (You want 7) Thats a foward shift case (rails come out the front vs a shifter out the top) it will work, but you would have to convert it to a top shift. People make kits for that.
Hey bud! What tcase is it I want? W56?
I looked at my crawlbox in my 86 4Runner
Looks like a top shift...I guess I want the same for the second box, w56?
Or do I just buy a new one with adapter and 2.28 off the trail gear website and also a set of 4.70 to put in my stock box.?

Close! A w56 is a transmission. The t case youre after is a RF1A. But yes, youll need a 2nd top shift case.

I like your plan of the crawl box and the gears for your case. That drops total tcase reduction down to 10.7:1. But even stock duals are great (5.29:1) , and you can always add the lower gears later.

If your ordering TG stuff, you can usually get it a little cheaper through summit racing with free shipping.

love some good transfercase talk in the morning. Haha.
