Here are two pics of gauges, the combo gauge is what I already in my 2 liter without the numbers. I see a local CL listing for the one with the numbering, the goal of this project is to have numbers on the gauge since I did a SMD LED retrofit of my gauges. Is this a direct swap out of the temperature module withOUT the necessity of a new temp sender? If I only need a sender, does anyone know the number? sorry for the disparity of the image sizes.

I'm assuming your going to replace the temp. module with a numbered temp. module. I think this is the sender you will need for the module change.

Simple answer is yes your 2.0 temp sender is the correct one for the 911 temp scale. I thought I would show the two side by side. 1st is the unmarked 914 next to the unmarked 911. Both have different hash marks on them but the temp range is the same. 2nd one shows the temp range on the factory senders of 200 C. Different end plugs but the same result. 3rd one is the aftermarket one that is 150 C.

Great, that the information I needed to know, thank you Mark !

You could always hook up what you have to a power supply (battery charger) and stick the sender into boiling water, then you can put a 100c baseline mark on the un-numbered gauge.
That's all you really have to know.

You can also use oil, and then you can mark it above and below 100 C. Just add a thermometer. Then you can run it up the scale and mark all your spots. While they are close to the same resistance and the same reading each will be sightly different. You should also add the proper length of wire with the same gauge as your installation. This will also effect resistance. Thus effecting accuracy.
