No body repops them. If you do not want stock any small box heater will work, the core is only about 10 x 6 x 2 inches. The original had an internal cable operated valve that regulated the hot water from the water pump or block. When mine went bad I just replaced the valve with a nipple and used an inline valve in the rubber line. Since our seasons tend to change quickly I did not even bother hooking it up to a cable, just lifted the hood twice a year to turn it off or on. With a little cable work you could get it to work with the original deluxe control if you have it. Deluxe fan switch is electric so that will work too. Vintage Air, etc. do make heat only units too.
