[TR] TR3 Heater Retrofit

[Michael Lang]

Bill,

Would you be willing to share a little more about the retrofit of your
new heater? I finally gave up on trying to patch the leaks in my Smith's
heater core, and the $500 price tag for a new core is a bit much for my
limited budget.

The main thing that I am curious about is how you dealt with the heater
hoses. Do the connections to the core poke through the fire wall or did
you find a way to hook up the hoses under the dash like the original
heaters?

Thanks,

Mike
