mechanical temp gauge location

you could likely tap it into the water port where the intake "blanks" that port at the rear of the block.

So remove intake and tappy tap tap......correct?

And, no bueno in the block drain....correct?

The spacer would be above the thermostat so although a fix, not the best of scenarios....also correct assumption?

Thanks Del! you rule!
