Depends whether you want to be "original" or not. I wanted a valve I could operate from the cab so I installed a 4-seasons 74828 manually operated heater valve and a generic choke cable operator. The choke cable handle is visible under the dash but very few people recognize it as an add-on.

There was another thread a few month's ago discussing heater valves.
