Push button cables

Search for a thread of mine a few years ago. I put new rubber hose on the outside to seal the tranny fluid and for heat shield silicone sheath w/ fiberglass inside. The later is an industrial product, but you might find on ebay or McMaster-Carr. The auto parts heat shields mentioned would work and my minivans use those on the power steering tubes, so next time at the junkyard grab some. You might also use thin-wall 16 mm silicone vacuum hose (ebay). Silicone is usually good to at least 500 F.
