[C10 - C90 Bill]

Depending on your Trans, but I would say what you have would be the 1L/1H, 2L/2H, etc as you have mentioned.

My Clark 5-Speeds with the 2-Speed Rears had the more unusual pattern:

1L
1H
2L
2H
3L
3H
4L
5L
4H
5H

On the 2-Speed Rear, your Last Gear in the Trans and Hi Range on the Rear will give you 1 to 1.
