The oxygen sensor is ordered from Underdog Racing, which I understand is a supporting member of this forum, for about $86 delivered. Can't beat that. Also went to the local Ace Hardward and picked up a couple 8mm w/ 1.25 pitch stainless steel nuts & lock washers and picked up some anti-seize (copper) from NAPA.

I don't have an 8mm 1.25 die for cleaning the threads. Do you think that is necessary or will a bronze bristle brush and some anti-seize be good enough?
