I want a 170* thermostat to replace my 195* stat. Where can i find one? summer is here and it is getting hotter. I also, am looking for a quality stat. I have had 2 of those Advance auto parts POS's stick closed on me. any suggestions? thanks

Look in the tech articles. There is a article on that 170* t-stat, and it gives the GM part #.
