Let's get this up to the top so people post in here properly (not that that has stopped anyone on this forum before...).
I bought a new Supermiata QMAX reroute kit from someone I know who didn't use it. All I plan on using is the thermostat housing (I checked but 949 won't sell individual parts from the kit). The one I bought works fine but since I installed a new sensor and the gasket on it fell apart, I have been having trouble getting a good seal. If you check my build thread you can see what I have done to try to make it work. The QMAX is configured so the sensor fits nicely with plenty of room for a factory gasket. One less thing to worry about for the future.
