I just looked up the price of the Billet Specialties o-ring thermostat housing, did you really pay $67.95 for it? I would bet that the Flashpower for $37. is made by the same people, but it's your money.
Billet Specialties makes all of their stuff in house and I doubt they would make the same housing for another company to sell at almost 1/2 the price of their own part.
