electric fan sensor location

Thanks for all the help guys! I ended up ordering an electric temp gauge That will fit in the small intake port. I really wanted the sensor in the intake. I think that would give me the most accurate reading. Didn't really want to pull the intake out to drill and tap after I just put everything including the a/c back in..and the housing spacer with the inlets sounded good,but I couldn't find one for a small block mopar.
Lastly I tried putting some copper hardware together to try and make the small inlet hole work but after figuring on spending around $15 or more for something that prob won't work that great and Woudnt look to attractive I just opted to bite the bullet and pay $50 for a new electric gauge.

Thanks again!
