question about gauges

I have been looking for indiglo gauges for a 91 saturn SC, it has the oil pressure gauge, I can only find the gauges for the ones with only the fuel and temp. So do they make these? If not what if I switched out the gauge cluster with a 93 gauge cluster without the oil pressure guage? Are the plugs in the back the same? Let me know if anyone has any ideas. thanks

i haven't seen glowing 91/92 gauges. i guess the people who make them don't do any research and advertise the 93/94 for all 91-94. i look in to swaping gauges a while back(i wanted the oil gauge on my 94), you would have to rewire the thing, plus a few things don't lights on the other gauge. some people just cut a new hole for the oil gauge and live with it not lining up. or you can make your own.
