I called James and ordered the rebuild kit, plus a bunch of other stuff I needed. Figured I save shiping costs getting it all at once.
I was going to take pictures, but to be honest, there isn't very much of interest in the heater box.
It took me 10 minutes to take apart and from what I can tell from the "kit" pictures, it will take me maybe 20 minutes more to put back together.
Just need to put the foam in and reassemble.
