Universal Oxygen Sensor - 1990 100 2.3 liter

[Theodore.Haug at rrd.com]

Greetings All,

I know this question comes up pretty frequently, so please forgive the
redundancy.  But what is the part number for the universal three wire
oxygen sensor that will work in my 1990 Audi 100 2.3 liter?  I know that
alot of the listers have sourced them through Autozone.  And I am not
opposed to splicing the universal unit in.  Any BTDT's that I should be
aware of?

Thanks to all in advance.

Cheers,
