Bosch universal O2 sensor where???

[Elliott Potter <epotter@abraxis.com>]

So I need a couple of new oxygen sensors for my '93 90 (V6, needs 2
3-wire heated sensors) ... I went to Pep Boys, Auto Zones, and Napas and
asked for a universal Bosch 3-wire heated oxygen sensor ... none of them
had a clue what I was talking about, and asked what car it was going
in.  When I told them, their computer would come up with some fancy OEM
part that costs $170 or so ... special order.

So how do people find these stupid things?!  Everyone always says
they're universal Bosch sensors and they cost 40 bucks, but I can't find
the stinkin' things anywhere.  Someone know of an Atlanta-area parts
shop that has these things?????

Thanks,
