I’m 10 years late but doesn’t seem like anyone knows jack about the shaft driven PTOs. The shaft driven PTO(power take off) winched have a driveshaft that’s connected to a PTO gearbox that is either connected to the Transmission(usually manual but I’ve seen some for automatics) or connected to the transfer case. PTO winches are meant to be used for work, not recovery. You can’t use wheel power and winch power at the same time due to the PTO unit using the gear power from the transmission or the transfer case via the engine. Once you engage the PTO You can choose what gear you want for the job, if you use a low gear the winch will be slow but strong and vice versa with a high gear. If you want to use it on your CUCV and it’s not a M1031(the M1031 has a 205 transfer case with a PTO port) you are going to have to change either the transfer case or transmission because nether one had a PTO port. If you don’t plan to use your winch ever day it’s not really worth the effort to install the winch, PTO, driveshaft, and make all the proper clearance for the PTO and driveshaft. I’ve heard of hydrologic PTOs that connect to the power steering but I am not familiar with that at all.
