The axles and driveshafts are not the problem. The GMC's Hydramatic had a 15.67:1 low range reduction that applied nearly 4200lbs of input torque on each drive shaft. This much torque and it does not take a lot of binding in the system such as a log or large rock under a wheel to create twisted driveshafts. Shock load is also another factor in broken shafts but this is not a real issue with the 302 and low ratios.
Reverse low range was actually 17.35:1 which is just insanity IMO. One of my rear axle shafts has the splines slightly twisted in the reverse direction. Crazy stuff man!
