Or you can buy a cheap brass Autometer adapter that will take your original sender and allow it to be used with the Vortec. That's how mine's set up, and it works great. The only thing is that the needle on the temp gauge isn't in the middle when it's at operating temp - but once you know what normal is, it's no problem. Sorry, it's been a while since I bought that adapter, so no part number - but they're under $15 and readily available. Just a metric thread -> NPT adapter, a very basic part.
