Graham,
The combination transmission-differential is a huge two-speed, (lo/hi with reverse) forklift specific transmission. It's connected through a torque converter and has nothing that could be reasonably used for automotive purposes. I'm sure the trans-axle is heavier than the engine! It would make a really fine boat anchor, though!
John,
The hydraulic cylinders, hoses and pump has been robbed off the F/L. The steering gear is gone and the steering axle is rusted fast, in a left-turn position. The little hard-rubber tires have sunken into the soil. If you could see it, you'd be amazed that the engine would start and run so smoothly. I don't know how it escaped destruction, too. The owner was just as mystified as I was, when it fired up!
