Yes, that's the incorrect sender if it has a spade terminal. There's only one sender type for the stock gauge, and it is for a 1/2 NPT hole. This is the one I use: https://www.amazon.com/gp/product/B000C9SM22/
If you need the sender to fit a 3/8 NPT hole, you can buy the 1/2 NPT sender and have a machinist turn and re-thread it. There are a couple forum members here offering that service. I had forum member A1971Blazer turn and thread mine. Other people had it done by brian mac.
