Hi Jeff, everything you need for the conversion is in the same place on the JD parts catalog. It's a little confusing because they only picture one seat, but the quantity required column lists 2. They are identical. It takes a good bit to convert these. You'll need 2 seats, both seat bases, the seat adjusting rails for the drivers side, center console, cover plastics, and all mounting hardware. I've highlighted the large components for you in this diagram. You'd also want to get all mounting hardware. The drivers seat mount base is #4 and the passenger seat mount base is #18. Hope this helps!
