Oh Boy.......I've got a water neck spacer coming from Hughes that I paid a small fortune for to get shipped to Canada. I too want to run an Autometer mechanical temp gauge but didn't realize that the probe may still hit the thermostat. Autometer has an adapter fitting that seems a bit longer than a regular fitting. Hoping this will do the trick.......I'm already $100 bucks in, what's another $20:BangHead:
