I want to replace the temp gauge sensor that sits by the thermorstat. I can't seem to find the part number. I found one online but not sure if it will fit. I tried looking up the 430 page manual but didn't see it in the cooling section.
I have a 67 M725 with the 230CID motor.

This is what I found "New SMP Engine Coolant Temperature Sending Unit Sender, TS4" on Ebay

Thanks!
