I changed out the heater box in my M1123 and for whatever reason, I cannot get the black diverter box to fix back on for the life of me. I'm almost sure this heater box I have goes to a M998 possibly, I want to ask have anyone ever converted the diverter box to the newer style? If so, how did you get it to fit? I'm close to just routing hoses through where the heat blows through all of the plumbing at the same time, but would prefer to have the diverter.
