Most any later year will work. On my '16 I wanted to use 5-1 steering gears, so I used the shaft, gears and lower housing from a '27. The nickel plating was weak anyhow, so I buffed the remaining plating off. The only visible difference in housings is the cover. The threads are all the same, so a '16 cover will fit on a '26 steering gear housing. The only real difference in the covers centers around the knurling around the edge.
