the unequal length is what allows the stability of pinion angle without fore/aft movement.

if you do what I said above, about mocking it up with paper, use pins as the pivots, you will easily answer these questions for yourself. in engineering we have a saying: "engineers will argue for an hour about something that could be tested in 5 minutes" mock it up with paper, you will be able to simulate longer bars, different attaching points, unequal bars, pinched bars, all of it. literally a 5 minute test. better than that, you will see it for yourself, way better than trying to interpret words on a screen
