Passenger side...
I'd like to meet the guy who invented rivets...and have a chat with him. Removing the 'feet' from the 4th Gen Seat.

The 'feet' reinstalled into the truck:

The 5th gen seat - the feet on this one are welded on; and I've already cut them off and ground the welds ground smooth and painted!

Line up 5th gen seat on 4th gen brackets - mark to drill; drill and bolt to 4th gen brackets; and install!

I'm going to take them back out once more, and since the 4th gen feet are bolted to the 5th gen seat; have them welded to the seat track. Even though I used grade 8 hardware, the welds are a bit of extra caution, if nothing else!

I've got the power lumbar and power seats hooked up via temporary patch harness. Am looking into how I want to build the full harness - need to source a connector for the 5th gen seats so I can re-pin the 4th gen wires to a new connector that plugs in.
After the harness, it'll be time to grab the switch block for the 4th gen heated and cooled seats, then connect it up to see if the 4th gen electronics will 'talk' to the 5th gen HSM module! If not, it will be easy enough to get some 4th gen HSMs and install.
More as it develops...
