    here's the catch 22
    T14 output is 10 spline . so OD is 10 spline also
    you do the swap your going to be 6 spline on output shaft
    going to need new bull gear for OD to work

    I will ask the guys at Novak about that. They did not say anything like that when I called them about my setup and asked what exactly I need

    Yes, the T-14 has 10 splines. You will need a new planetary gear for the overdrive that matches the spline count of the new main shaft for the SM420 (6 splines). Or, you could leave off the overdrive and use a 18-8-23 output gear that has 6 splines.

    I originally desired a PTO winch until I learned about the limitations of such a system. If you do go and spend all that time and money getting a PTO winch setup together make sure you do your research first and decide it's what you want. I love old school tech and I did want a PTO very badly but after looking at the pros and cons I wound up going electric.

    I’ve been taking peeks at it all day. It’s kinda growing on me. That part of me is saying yes, paint it and put it on your bumper!:twist:

    I have the AA adapter, unused, for an SM420/dana 18. It is the type that replaces the whole shaft. I don't know if it is acceptable to post prices and personal contact info in this forum. please PM me here.

    The 8074 was an interim winch between the more or less current 8274 and the older Warn 5687 (also referred to as Warn 6000) The Warn 5687 is a duplicate of the Bellvue winch that Warn purchased I have working examples of all 3 in the basement

    I found a local who had a rebuilt SM420 with the 10 spline spud adapter for $300. I’m picking it up on Tuesday. Looks like I’ll have something to do this winter.
