Mike,
I took the time last night to practice the procedure on my parts car.
It's actually not that big a pain to remove the entire heater assembly,
certainly not when compared to the rear end, indeed! I think on a '67
its a piece of cake compared to later cars too.
The good news is that I'm not even certain if the heater core is bad yet
or not. Could be the valve. I'll find out when I flush the radiator
this weekend and try blowing our the core with some compressed air.
As for seals, we've been messing with a wide variety of rubber
gasketing, weather stripping, felt and other materials to act as a shock
mount in a new product we're developing, so there's a ton of sealing
material all over the office. I think I'm set!
Cheers,
Andy
