I had an issue on my '64...a guy rebuilt the transmission for me, and forgot to secure the cables. One touched exhaust...it was a mess. I took some fuel line and some sort of sealant (I do not recall what kind for sure), split the fuel line lengthwise, wiped down the cable housing with alcohol, smeared the inside of the fuel line with sealant, and fit it around the cable housing. I think I zip-tied it in place. Drove it for years like that, and it's been in storage for years--never a drop of leak again.
