    Why don't you run it off of the t-case?
    That is where I had mine mounted. The gears are cut oppisite of each other from a '205 Vs '203/SM465 application. So a box off a 203 will fit a SM465.

    Advantage to using the tcase mount is you'll get 4 speeds in one direction 1 in the other. All depends on how you spool the cable.

    Part #s will only do so much, there are so many different styles available. IF you mount to the SM465 you will need to find a PTO box that has a reverse in it. The counter gear shaft in the trans only goes in one direction. If you mount to the tcase a single speed PTO box works just fine, use reverse in the trans to unspool.

    I'll see if I can get a pic of the PTO box I have.

    Diesel Dan that's a great idea. I hadn't thought about using forward and reverse to control the direction of the winch. /forums/images/graemlins/thumb.gif

    Question about installing the pto box, Do you just pull off the pto cover and bolt on the box, or do you have set it up like a ring and pinion (with the corret backlash or something like that? I can see the pics now thanks

    When installing a PTO you have to set the backlash. To do this you use different thickness of gaskets(shims).
