Original shifter knob thread?

[French demon]

Hi buddies

What's the shifter knob thread on my manual 3-speeds on the floor lever?
I want to buy a correct shifter knob, but I don't know the thread.
Thanks

For the A-230?

If so, two different threads were in use at the same time.

3/8" RH fine thread & 3/8" LH coarse thread.

There are also smooth and pebble grain shifter knobs for each thread variant, for a total of 4 different possible knobs.

Yes, A-230

RH and LH mean clockwise and counter clockwise screwing?
If yes, I have to check my lever thread screwing direction as by now, it is topped by a modified auto trans shifter knob.

Good grief!!! I never knew they used LH thread!!! Most anything I've run into has been 3/8 SAE otherwise known as NF (National Fine)

Yes.

Thank you, you've been a great help.

I had a look this morning, and my lever has LH coarse thread.
Now, thanks to Alaskan_TA, I also know that it's 3/8 diameter.
Just have to find an original knob now...

Is the LH lock nut still there? If not you will want one of those also.

Of course not. It would be too much simple.
