Axel shaft length

Anyone know the Stock axel shaft length for G body 7.5 26 spline I come up with two different lengths with 28.438 and 28.437
this is for a street cruiser just looking to upgrade from stock.
Any and all help is greatly appreciated.

That's what I thought lol but why even give two different dimensions so close together. :roll:

Those are the exact axels I am looking to purchase.
Thanks everyone for the help.
