M1 plumbing question

So I just realized there is no port for a mechanical temp gauge or heater return line. I've never used an m1 manifold before all the other intakes I've used have provisions for these accessories. Any suggestions besides no heater and electric temp gauge which I don't care for? Guess I can T off the port going from water pump to intake but that would look cluttered. Just fishin for ideas and even better pictures. Thanks guys.
