Gauge help

[BlueSteele]

I'm changing the Atari electronic 3 gauge setup on the SSV with dial gauges, however im finding it hard to find the right replacement. For instance; the oil pressure gauge on my car when driving can hover between high 200 to mid 300's, yet looking at the gauges available, I notice the MAXIMUM number that the dial gauges read is around the 140 mark only??? im very confused. Does somebody know why there is such variances in car gauges, and in turn where I could find dial gauges that would replicate the same numbers of the electronic ones in the car now?

Thanks

perhaps your first gauges are reading kpa and the aftermarket gauges are reading psi.this could explain the difference.
