It is the center gauge in the console above, as you can see it is a 1/4 sweep then a large reserve area.
See if John is still doing the 904 gauges, he is more reasonable than Palo Alto. Or you can build one yourself it you so desire.
This will let you know what your in for. I stumbled across all the design and paper work I have for the kits I did. It is public domain information, so you can use it to your hearts content. I can post the design pieces if you want.
Another option is to use a 930 Tach, and put the fuel gauge in there instead of the oil pressure, and keep all the oil gauges in one window.
BTW, you can also do a quad gauge using a 924 gauge, and then a custom back plate. Please get rid of the Madonna cone bras if you do them.
You can also change them all out and use
Speedhut for them. Modren instruments, shallow mounting and fully customizable for a 5-6 uncle ben's.
Go full 911, and install a Getty Dash.
So many options just depends on what you want to do.
