Pinion depth

What yall think run it? I was told don’t worry about centering between toe and heel. Used stock shim since it gave the best pattern so far

sure seems like a lot of slop between drive/coast. is your lash within spec?

the overall pattern looks like it has good contact according to the examples you posted.

That is similar to how I set my last Cobra up, the only concern is if you can handle some whine with it. Contact patch looks OK just a little tight on the pinion depth.
