I need some schooling on my new A833!!!

AFAIK, it's not possible to swap those, because;
The helix angles are different , like the Muncie "Rock Crusher" stuff, versus regular Muncie.

But amongst the regular 23spl stuff, AFAIK, the M/S low-gear will swap amongst the three ratios I know about. And I think the m/s second might, between the 2.47 and the 2.66
But each of the three front ends are otherwise different.

Here are the only regular street ratios I know about, with 1x23 inputs; not including the od boxes.

24-29-34-35, ratios are 2.66-1.91-1.39-1.00
31-27-23-17, the standard "wide" ratio

25-29-34-35, ratios are 2.47-1.77-1.34-1.00
30-26-23-17, the T/A "close" ratio

22-27-32-35. ratios are 3.09-1.92-1.40-1.00
33-29-25-17, the Commando "deep-low" ratio

Whether or not it is possible to swap inputs, among the "coarse-angle" boxes I don't know.
Hi AJ, I've heard you talk about the Commando 4spd. Do you know what the gear splits are for that? And do you have a recipe for one that will see a lot of highway miles? Currently have a /6 and about to do a LA 360 swap. Still kicking around rear end gearing. Thanks.
