Quick question about VLSD and axles.

[MrChow]

First off I have searched the shit out of this. I think I have my answer but anyways I just want to make sure.

I have a base S14. I just got a "SR20" VLSD pumpkin with 5 bolt axles.
Should just bolt up after switching covers. I let my friends do the work at there auto class. They found that the axles are different lengths and the teacher basically said no after because that they don't match up. Blah blah. So we just put the stock stuff back on.
Just getting back home and when search about this. I just went and looked my axles and there different lengths....

My question is that does the S14 have different length axles too?
Also does that mean there a driver's and passenger's side to the axles?

Off question about gear ratio with diff came with the 4.3 gear ratio??

Thanks
