I don't have time for a thorough and detailed reply. But I'll throw out a few issues for your consideration...
I'm not totally familiar with your Tucker's configuration, but I believe it has an Allison transmission, and a factory Warn winch. Honestly, I had never seen a factory blade installed on a machine also equipped with a front Warn winch until this thread with such a machine listed for sale:

Note how the winch mounting is different, putting the winch several inches higher. Part of the blade frame is also different from the standard Tucker six-way blade system.
On my Thundercat project we changed the engine and installed an Allison AT-545. On our installation the additional welded members for the blade interfered with the transmission pan. That required modifying the pan. I'm not sure if that would be required in your application or not.
Another part of the blade frame is different between 1500 and 1600 series machines. With the longer tracks, a 1600 series needs that frame portion to be longer than a 1500 series machine.
Lastly the six-way valve. What are you going to use?
