Forward Backward motion with Mazda shifter and 02J box is correct

But as You see on Mazda shifter box there is space for third cable.
Let’s switch mind that Mazda box is now in X1/9.
There are two options:
1. Wait till I find part number of Right side lever.
2. Modify (it is not hard) existing left lever to be used on the right side.
Mazda box is not small, but it can be made narrower- to be 105mm wide or less for unknown reasons yet.
