Likely any pickups of the same generation ('89-'95) or 2nd gen 4Runners. Should be a 4-wire connector (heated sensor) vs. the unheated 1-wire sensors on the earlier trucks. Not sure the year of the switch over. Should be able to pop the connector off the sensor in the donor vehicle and see if it looks the same as your sensor (bring your sensor along for a test fit if unsure).

oh also if cali spec #1 or #2 sensor? Pretty sure 4crawler is right, I am just gonna cross reference actual o2 sensors, but the plugs might cover a wider range.
