Part for a Golding Improved Pearl 8

Does anyone have the specifications for a treadle crank stud for a Golding Improved Pearl 8? It attaches the treadle connection (rod) to the treadle crank.
Since it has reverse threads, I can’t do trial and error at Lowe’s or Home Depot.
Bolt size, length, how long is the shoulder, etc. Anything that will help me specify the correct thing over the phone. Thanks

If you can’t find it….

One could re-tap it for a known reverse thread size/count

I believe it is a 3/8’s -16 left hand thread, 1/2” shoulder length and diameter. Length of threads about 1/2” as well.
I have made several.

You can obtain the required L/H shoulder bolt from McMaster- Carr Part number 90324A152. approx $7.00
