Ron, I did a little research on that a few months ago and found that the only choice was salvage yards at the time. My 190XT I was removing the wire to replace wire and test the heater and broke the outer nut off and it. And the heater was good, so I removed the inter nut and was able to put the wire in between the inner nut and stem that goes thru the porcelain.

Thanks for the info. We found the air heaters on a Gleaner combine and a couple of diesel tractors in the salvage yard.
