sweet, i want the least amount of electrics, and set up with manual shift
but im sure it would need a computer to keep the oil pump going.
the manuals are far to high geared, i looked at a set of 3.1 crawler gears from the states but they arnt very cheap.
and changing my diff ratios gets tricky as i have a 4.8 hi pinion in the front.
