Early 1958 high-horse fuelies had a firewall grommet that the distributer driven tachometer cable ran through instead of the neoprene seal as used in later 58' through 61'. Does anyone make these??? If not, does anyone have a spare that they would be willing to sell? If not, can anyone at least email me a photo of one since I really don't have a clue as to what I am looking for. Thanks again!!!
