Thanks T, mini. From what I understand now the thermostat kit includes the necessary O-ring and the other is not necessary. Unless I hear back about this I will probably buy both anyway as they are 83 cents and I'd rather not risk it. This probably sounds ludicrous to people who have done this job before, but I have not, so I'm kind of feeling my way through it.

Thanks again!
