Just to confirm the correct oxygen sensors I need for my 1998 would be STD part numbers SG413 (upstream, front) and SG558 (downstream, rear) Some of the listings I see list a number of SG sensors that fit the 3000GT, but I'm assuming the above two are the correct ones for the two sensors in the front and rear O2 housings. Also assuming they are an OE fit so I don't have to splice wires.
