On mine (a 78) there was a trough under the accelerator for when it is "floored" so to speak as the mechanism on the back would stop it going right to the floor of there wasn't the trough to allow it! If that makes any sense at all....
I was going to list it yes, but didn't no if anyone would be interested due to the removal of the tubular section
I'm still interested as I want it to repair my own. Would you mind messaging me price location please?
