904-style gauge help
 

I'm about to buy one of these gauges. I would like to upgrade it to have an oil pressure gauge with a calibrated scale rather than just the 1-5 numbering. Where do you get the parts for this? It looks like maybe I locate an old dual 911 gauge that has scaled gauges for oil temp and pressure-is this right? Then what senders can I use? Thanks!

FYI, the 1-5 is a scaled gauge, it is Bar which is about 14.5 psi. 911s came both ways, so you could find one with psi.

The temp gauge is the one that came with no scale, earlier 911s had the temp number markings and you can buy the replacement module (for the 911 guage) with markings.

If you use the 911 modules, then use the matching year 911 senders. These changed through the years, so you really need to match the years.
