TRISTAN - Your question, "Your making me wonder about the GD... with 14hp, bigger tires, and hauling a lot of weight over rough ground, is this going to be too much for the stock tranny / rear end?"
If you break a GD CC you're doing something you should NOT be doing.
I've described the convoys of trash carts they pulled around IH manufacturing plants here before. They used GD CC's at first because that's all IH made. I supposed before CC's they used Cubs & Cub LoBoys, but that was before my time. They used Hydro CC's because they withstood the constant starting of heavy loads better than the little dry clutches did for five 8-hour days a week all year long. Plus we all know about replacing clutchs in NF GD's takes a while. Took me about two hours when I replaced my T/O bearing last summer.
The only problems I see in your setup is with the RED spring, clutch pedal effort will be through the roof, and the Q/L 3-pin driver is prone to cracking stock.
