I have an '04 4Runner, and I'm planning a 4WD IFS conversion. I have an A340E at the moment, and plan on converting it to an A340F through the change of output shaft and oil pan. I know that first gen Tacomas have a manual T-case, but I'm wondering this. Is it full time or part time 4WD? Is it just a hi-lo rail, or both 2-4 and hi-lo, and if full-time 4WD, nothing connected to the 2-4 rail? Would there be any other option for a twin-stick T-case that would fit the A340F?
