Are new axle shafts and a new differential all I need to do this? I'm thinking about chromoly in the back with a lunchbox locker.

28 spline 10-bolt to 30 spline . . .

I would double-check the wheel bearing and seal (that sit on the outer part of the axle tube) to make sure they are the same diameter, but I think they are same.
If you are upgrading from something like the stock open diff and want a limited slip or locker anyway this probably is a decent plan. However not sure if I would spend the time and money on this to only get the 30-spline shafts.

All that is different is the shaft diameter and spline count.
The carrier itself needs to either be bored out to the correct Id, or get a 30 spline carrier. I just did this in the front of mine. I ground out the 28 spline carrier. I can find a link if you would like pictures.

copy and past from my thread. This was for a front 10 bolt, but IIRC they are the same front and rear..
Then I got my locker installed in the carrier, and took the 30 spline shaft to see if it fit good.... Ohhhh 30 splines shafts don't fit in the 28 spline carriers. Ugh .... (Didn't know this)
Checked the OD and ID of the 30 spline carrier that the locker came in, and it's the same OD as the 28 spline carrier, they just drilled it out more. So I figured what the heck, some grinding is easier than shimming gears.
28 spline carrier
30 spline carrier
Precision milling device....
Carrier in and the shafts slid in no problem

Thanks . . .
Thanks guys . . .

Fyi, the one with the bigger ID is in fact a 30 spline carrier I had, BUT at the time i had never done a gear swap nor did i want to mess with installing bearings etc. So i was dead set on getting the current carrier that was correct with the pinion to work.
Some tape over the bearing to keep shavings out, and some time with a die grinder made it work.
Just some words of wisdom, make sure the seal surface on your shafts lines up with your inner axle seals, I installed my ten factory chromos up front and they wiped out my seals. Compared them to the seal surface on factory which is about 3" long. The chromo shafts only had about a 1" length of the smooth seal surface..
Its another one of my winter projects to rip the axle down and replace them AGAIN
