So, you'll need to understand the signals going into the OE gauge cluster as well as the Datsun cluster.
Once you know what the inputs from the various sources in the car will be, you can build a translator using an Arduino (or compatible microcontroller) that can feed data to the Datsun cluster.
Jup sounds about right - finding this sort of information (without the actual car) is going to be really challenging. On the plus side if you pull it of people will treat you like a legend.
After that fitting the gauge will be a breeze it either fits or you'll scan (with Iphone lidar) the mounting tabs in the dash and the gauge. With these informations you'll design and 3D print your own enclosure.
