[V8] O2 sensor crossover 02 A6 Q, V8 ~ ? Mustang 5L

[John Zofchak]

Greetings,  I have an 02 A6 Quattro V8. Which needs new cats.
I have Davico direct fit replacements but may need to replace the four O2
sensors if they don't come out well.
Heard on here that there is a crossover for these sensors to a Ford Mustang
5L V8.  But I don't know the correct part number.
Does anybody know what part no. that would be?  And any feedback on using
them?

Thank you for your time
