I'm not sure if this is a stupid question or not but I am trying to replace the original throttle cable on a 1970 Plymouth Barracuda Gran Coupe 318.
My problem is the "original" (to the best of my knowledge) cable has this weird square plastic thing surrounding the throttle cable on the inside of the firewall, this plastic piece is not present on the replacement cable or mentioned in the mechanic's manual and is keeping me from taking out the old cable. It originally had a random rusty piece of metal running through it as represented by this rust colored line I drew in paint:
