I have a 47 Clipper with Overdrive and I am installing a new speedometer cable. How do you fit the cable through the firewall? Do you have to remove the firewall grommet and slip the instrument end of the cable through the firewall from the engine side? Also, should the new cable be lubricated before I install it and if so, what lube should I use?

Yes, the cable should be lubricated. You want to use a fairly light lubricant, not a heavy grease; I've always used "white grease" like LubriPlate or Pennzoil. Others I know have used gear oil with apparently good success. Don't lubricate the top 3 or 4 inches to prevent grease from working it's way into the speedometer head.

Probably long-known the below pictured method to oil the cable by help of an electric screwdriver.

How true! To avoid that trouble use gear oil and after oiled let the cable hang for a day to drip off.
