Is this gauge in pic pegged?

[WIDESIDE72]

There are several other threads regarding temp gauges right now. Originally the temp gauge would have read a little higher on ther scale than what yours shows. Logic would say if you used yours as is, if the truck overheats, the gauge will still only register mid scale. IMO you dont have the correct sending unit. Its the one in the head for the gauage. I bought one off ebay and it works great. At normal operating temp its just to the right of the left line, a little farter right than yours. Off and after sitting overnight, It is all the way to the left. It was pricey at $37, but works.

Someone posted one from classic part for $8/$9, but i dont have any experience with it.
