Alright, a newb needs some things explained to him...
First of all, I have a 1986 4Runner, with a 2.4l diesel swapped into it. It has the R150 transmission. I already have a transfer case on there (duh), so if I want a dual case set up, do I buy a 'single' transfer case, and stack it with the existing one, or do I order a dual case, and completely take out the stock case?
Secondly, which one do I need? I'd like to be able to crawl damn slow, especially as I get larger tires onto the rig, so which gearing should I be looking at?
Wish I didn't have to ask such dumb questions, but I guess I have to start somewhere.
