Scotty, I have a 1998 Toyota Camry with about 258000 miles and a hard P0135 code for the rear O2 heater circuit. Is it worth it to try and find a junkyard replacement sensor, or would I have to replace both upstream sensors?

No.

Why would you need to do that if only the downstream sensor has a problem? Have you checked the wiring to see if the sensor heater is receiving the proper voltage?
