diff in o2 sensors?

[transAMchubby]

im doing headers tomorrow. after doing some searching here i couldnt find my answer.

99 t/a. installing pace setter LT (race) and pace setter ORY. will be getting tune so that i pass emissions in MO.

WHAT O2 SENSORS DO I NEED TO GET?
i checked site sponsor gmpartsdirect.com but do i get the vette o2 sensors for 1997-1999 vettes, 2000-2004 vettes, or something else? i would like to stay away from o2 sims or extensions. i heard its the ones from a c5? i dont know though.

thanks ahead of time!

As far as sims, you wont need them since you allready plan on getting a tune. I would honestly just pick up two 12" extensions and some stock 02 sensors and call it a day.
