Front diff questions

[69-350]

In just a couple days, my 97 K1500 will be sitting 6" higher. So far, with 10 or 11 grand into the truck, I still cannot see the end of my plans. Anyways, the next thing will be 4.56 gears and if I can, electronic or air lockers front and rear ... then a winch bumper, maybe a rollbar, plenty of lights, hopefully a lottery, maybe some cherritable rich dude, this and that, etc...

Anyways, my question, is what do the 88-98's have for a front end, in the half tons? I am pretty sure the 3/4 and 1 tons have a 9.25" 33 spline. Do the half tons have a 8.25 30 spline?

My next question, does anybody make a friggen locker unit for the front of a half ton axle?? ARB airlockers, Eaton lockers (electronic), Auburn Gears (electronic locker also) etc... I can't see anybody that has anything for the front diff on one of these half tons.

And gears... 4.56 is just right, and as I'm told, the biggest you can go in half ton differentials. Who sells a good set of gears, and where can I get them?

Right now I'm wishing I would have ordered a 3/4 ton lift kit and just converted the truck. Would have been easier (and tougher), and I don't believe you can use a half ton lift kit with 3/4 ton drivetrain, although from what I've seen and helped with and worked on with the lift kit (which has been a lot of it), I don't see why you couldn't. If it's possible to use the existing lift kit, and just throw a new rear end in, and new 3/4 front diff with CV shafts and all that, I'd later down the road do that. Brand new wheels or not, I'd convert to an 8 lugger, if that's possible?

And by the way, what are the rear diffs? 10 bolt 8.5" 28 or 30 spline?
Anyways, some answers from people who know more than me would be great. Thanks.
