Two questions requesting clarification on a heater core/box installation on a '65. I got the gasket kit and need direction on what to do with the grey foam gasket the goes on after the black gasket on the interior of the firewall. It appears to go on the outside of the box, conforming to the contours of the exterior, rather than completing a seal of any kind. Am I wrong? If that's the way it goes, why is it there (just for looks?)and do you use adhesive to hold it in place? If so, a spray 3M adhesive?
Other question: I've seen different illustrations on what to do with the "donut" ring seals that go arouond the heater core outlets on the engine side. The most popular method shows them on the outside of the heater box fiberglass cover, but I've seen one descriptiion that says you should put them on the inside of the cover after the black seal and between the cover. Neither option seems to seal it particularly well. I guess I could really jam them in there, but don't want to botch the whole deal. I'm wondering if I should use an adhesive and what that should be....
Too many questions, too little knowledge. I'd appreciate any input.
