Interested but what would something like this cost with an adapter and crawl box with twin sticks? And as far as 21 spline and 23 spline I think I'm confused. The back of my 86 runner tranny I'm guessing is 21 so I would have to have 21 on the input correct? Then the option of 21 or 23 in the middle of the 2 transfercases I can choose 23 for strength is this right?
