Reset knob on rally clock

[72rallye]

Does anyone have a idea what size the tubular nut is on the reset knob for the clock?

its got to be something like a #4 as it is pretty small

Since you didn't say "trip odo AND clock" it sounds like you may have the one for the speedo's trip odometer, they're identical.

Well, I got ambitious, hope this is what you were after.
OOOPS - Just noticed your nickname "72".
These pics are for the 1970 resets, I don't know if 1972 is the same.
Maybe this info could be useful for someone else.

More pictures (in inches). The inside is measured with no threads, the threads start about 1/16" down from the opening. I also measured the threaded part of my clock reset cable ~ .071. That's +/-, it's not 100% round. I also added a pic taken off the web (Classic Industries), the barrel nut sure looks to be the same.
