Regarding the old Warn overdrive unit I had a 1968 Jeep CJ-5 with not only a
Warn overdrive but I also had a dual drive power takeoff on the tranny as
well to run an 8000 lb. mechanical winch mounted on the front. The rear of
the PTO drove a simple spline shaft which I had coming out just to the right
of the hitch....great for a windlass or whatever. I never in 6 years had a
problem with the universal joints if I greased em on a regular basis. Wish I
still had it today...oh yeah power was a Jeep factory supplied Buick 225 CI
V-6 160 HP With 4.89 ratios F&R. Not very fast but go anywhere.
