2 exhaust issues

First, where do you guys get you o2 sensore. i was just quoted 210 from mazda and there are only 6 left in the usa? Will the bosch from autozone work well? Will it hold up to the egt?

Second, is there some kind of trick to keeping the flanges tight. I now from the header flang to the tailpipe have fresh grade 8 hardware, new stainless exhaust piexes and coper gaskets. I am forced to tighten everything every 2 days cause it keeps loosenong and its getting annoying.

Please excuse my typos, my android phone isnt as rasy to type on as my old tp2.
