so i finally got my rear o2 sensor(97se 2.5) out with a lot of heat and bp blaster. now the problem im running in to is that none of the shops i go to have one in stock napa,autozone,advanced ,ect. they pull up the pn but the connectors dont match. but i had one of the shops grab me a front one and the connector matches perfectly but the wires are about 8in longer . so hears my question can i use a front o2 sensor for the rear one ?
