Hello, I have a question about the 68 RS I just bought, This car has some odd options, and that has made me want to investigate things, I have NO documintation on the car, I have the car and a title and have worked my way back through 10 owners 2 to go, The good thing about this car it is original untouched except for motor and trans, I do believe the car to a 4sp car, it has a muncie in it know, so in doing a search on the speedo cable and where it is suppose to go through the firewall, I went out to look, in order for it to be a muncie car, the hole was to be to the right of the steering column, I could not find a 1inch hole like the one under the fuse box, for the automatics and saginaws, the only one I found was small and had a small bolt holding in the rubber grammet, and the rubber hangs out on the engine side about 1/2 inch. If this is the correct whole, it would of had to been a two piece cable, if not what is this whole for? here is a pic of the hole under the dash.
