I advise a Stant Superstat. They have jiggle valves installed already for the 2.2/2.5 thermostats, no drilling necessary. Better quality, too, IMO

I would imagine they do, chuzz. The Superstat is Stant's "premium line", so I imagine that all the bells and whistles you can put in a thermostat are in there. None of the other 2.2/2.5 thermostats that I've seen have them.
