Where can i get a 80C/176F thermostat ??

[Coupe E36]

Ok, just finished putting in a new waterpump, new alum. thermostat housing, and replaced the stock 88C (wich was pretty damn bad) wit a new 88C did a really good Bleed and everything.. So since i had the fan off, i put everything back together but the fan, just to feel how it is w/out the fan.. took it for a spin, everything was ok, needle never moved above the middle cruised around for about 20mn, then finally hit traffic, and thats when needle started to move up so had to turn the heater on full blast, and kept it from moving up any higher.. finally got off the freeway, and when more air flow started to come in needle went back to the middle :12: ..

well wat i am trying to say, is i love the car when the fan is off, everything was silent, and i can really feel the performance difference, taking off was a lot smoother rev. faster and everything.. So i am trying to find a place i can purchase the 80C/176F thermostat and fanswitch so i can run w/out the fan.. Anyone know where i can buy one ? and how much they would cost ?? only reason why i dont wanna buy the kit from understeer is because i have all the stuff the kit comes with except the thermostat and fan switch.. anyone can help me, please ?? thanks..
