Project "Chihuahua" '65 Formula S Restoration "Estilo Mexicano"
Update: Brake booster factory firewall rubber seal is not really serviceable and shipment cost from the USA makes it prohibitive to secure the factory correct replacement. I found a local hardware store had an everyday plumbing pipe seal that seems to fit except for the oval opening for the brake rod. I will try to expand the round opening to a more oval opening in the following weeks by way of inserting the handle of my gasket scraper in the opening. The factory rubber has a little slit designed into it that hugs the small metal frame it rides in to keep it from popping out. The generic replacement I found of course does not incorporate this provision. I could try to make a slit "ring" with a Dremel tool or razor blade, I could try some kind of rubber adhesive, or I could just hope it stays in its place on its own (I haven't decided on a course of action yet).
