[Healeys] Replacing Heater Valve on BJ8

[Bob Spidell]

Thanks for the reply. Having the heater on the bench makes for easily 
replacing the valve, but you still have to wrangle under the dash to get 
the inlet hose on the valve. I'm wondering if I need to disconnect the 
hoses in the engine bay so that they can be pulled out far enough to 
dis/reconnect them (I'm leaning that way)?
