Does anyone reproduce the rubber dust boot that goes on the underside of the automatic floor shifter of a 66? I am converting a column shift car to floor shift with console. I have already welded the shifter hump to the floor pan, but I was looking through the catalogs and did not find the dust boot. I am considering using the Shiftworks shifter instead of an original, as their shifter looks like it could have a solid pan installed under it since it uses a cable that goes through the tunnel in front of the hump, and is sealed by a grommet. I have a line on an original Powerglide shifter that I could retrofit with the correct detents for my 4L70 trans, but If I can't get a seal to keep the heat and fumes from coming up through the shifter hole, if will be of little use.
