Default Replacing O2, Sensors Bank 1 and 2 Upstream front

Quick question. I am going to replace the 02 sensors for Bank 1 Sensor 1, and Bank 2 Sensor 1, 1999 Lexus ES300. Denso has the parts 2349007, and 2349009. Do I really need to get a different one for each. Is there a universal part number that I can use to replace both upstream sensors. The site I am on right now says that, Upstream front Denso 2349009 is $89, but the Denso 2349007 for upstream rear is 120$. Pretty sure the Denso 2349009 would work for both. Please let me know if I need two seperate pieces.
Thank you

You know what's weird, NTK has one part number for both. I bet the Densos, probably being very very close to the OEM designs since they made the OEM, only differ by the wire length or some other mounting concern. Check RockAuto's catalog, it should be accurate for this.

EDIT: Lol, saw your other thread and artbuc answered it correctly. GL
