I've been working on my old '68 Power Wagon and finally got the '93 5.9 Cummins with a Fuller 10 speed mounted and most the bugs worked out. I also installed a low direct high Brownie box, sure makes for a quiet pleasurable drive at 70 mph on the freeway at 1,800 rpm. When towing the mighty D4 just switch it down to direct and away we go.
Here are some of the of my latest pics. Don't you just love that pretty yellow???
