Need temp sensor for rally gauge part number

Jason and I recently Converted my gas gauge to the rallye tri gauge rallye setup. As I only had a idiot light for temperature, now I would like the gauge to work, I'm assuming the sender is different, anybody know the sender part number I need? I already have Auto meter gauges just would be nice for the gauge to work, and harness was modified by Jason. Thx for the help

 

Shouldn't the cluster have come with the proper temperature sender included?

 

Napa carries it also. It doesn't look quite like the original (if you don't care), but works fine.

 

X2 on the lectric limited version. This one worked perfectly when I installed it for my rally gauges.
