My driver showed me his car a few years ago. 1995 model, 12v 6BT, Bosch P7100, Spicer 5sp/OD, I think it had about 295k on it and was running just fine. When you listen to them run through the gears you get the impression that it's full throttle every time unless somebody is in front of them. Mitch.
