Ignorant D30 axle question.

The question isn't ignorant, I am. I've tried to educate myself about this to no avail.
So, the stock <3.54 open carrier is smaller than the stock >3.73 open carrier.
Are the axles different lengths to accommodate the carrier size differences or is the carrier size difference a non-issue?
What I'm looking to do is add a TrueTrac for 4.56 and wondering whether it mattered, axle-wise, what size carrier came from the OEM.

I know they're both 27 spline. I'm considering 30 spline but haven't figured that out yet, either. I'm thinking I would go with some RCVs if it all works out.
Any links to threads or references?

This would be for a '14 Sport S 2dr.

It's never easy, is it.

Fortunately, I'm patient.

But along the lines of "never easy"...trying to find fender flares. Need 'em...2.5" wider than stock.
They all seem to be flat/same width or flat/narrower or not JK or...
