Very nice info! The 14 bolt should handle pleanty of abuse for years too come.
When swapping mine out under the burb, I had to modd some of the same area's.
Although I started with a NNBS SUV axle, the older ones are better for adding A/M axles to.
The Newer Modles come with smaller outer bearing journals vs. the standard size equipped in the older ones. All this equates to smaller non replacable axle shafts.
Since I Was soley intent on narrowing my axle for proper fitment, I purchased a similiar axle from an 89 W/T truck. I cut those ends off the tubes,grinded the welds down adn slid the bolt plate @ 2" forward for the disc brakes to work.
All in all I finished up with a bolt in 14 Bolt equipped with thicker High alloy A/M shafts combined with a tru-trac diff and OEM gears.
With over 7000lbs (truck and 4 adults) in 2wd the new blower smoked the rear tires all of 1st and half of second. What a smoke show!
in 4wd?? well the 4l65 lasted @ 5 seconds.
4l80 going on now.

Any chance you have pictures of your setup as you modified it??? I have both 88-98 style 4x4 and one from an 06 V-max. I also have enough G80's for everyday of the week...
I have the older style on apart already but have yet to crack the newer one open to see the diffrences you are referring to.... any pictures of the differences would be great!!!

No unfortunatly i don't, It was a frustrating build, My mind was toast tryin to get the outcome i wanted. Spent a lot of money, and eventually ended up with what i set out for...
with some extra goodies. Lol
The 06 vho axle has smaller outer bearing journals, along with smaller axle shafts that are NOT avail aftermarket. the spline counts are identical as the older versions just the shafts are not as big.
I used the combo of the two.
Narrowing the rear axle tubes 3/4" ea.,By cutting behind those reduced bearing journals Then cut the oldler axle tubes off @ the flanges,removed the welds and slid the flange to the correct offset needed and welded them back onto the my new axle.
Purchased the larger A/M Axle shafts from Randy's ring And pinion with the lenghts i needed along with A detroit tru-trac.
It took two axles to make one. Kinda wastefull but I have one bad **** 14 bolt under my sub that can take a beating!
If you are planning a build and have to narrow it I would recomend this to be done,just for the larger axle shafts alone,Just the alloy is 25% stronger, Add the extra meat in dia.
And it would be that much more.

It was about 2 grand for everything, but I had alot of nice parts put in.
Axle w/ tires - $440
paint - $15
ujoint -$25
ujoint straps - $5
gear oil and additive - $20
simple swap kit (perches, shock mounts, ubolts, ubolt plate) - $120
eaton lsd - $500
ring and pinion - $350
yukon complete rebuild - $180
labor for ring and pinion setup and spring perches - $360
misc hardware - $50
total - $2065
If you find a 14b with the right gears and you keep the G80 and dont rebuild it, then your looking at about $700 if you get the axle for around $400.

Also, I typed this up for another forum, but its still good info:
I just spent the last 2 hours trying to piece together this info, and just so its out in the internet, the stock 10b GM axle, has a S44 pinion yoke, and the 4" aluminum driveshaft on some GM trucks has a 1330 yoke. The stock ujoint is a 1330-R3 S44 conversion joint (spicer 5-793x).
1310 dimensions:
Overal width - 3.219
Cap width - 1.0625
Outside snap rings
1330 Dimensions: 1st version (the one on the aluminum driveshaft)
Overal width - 3.625
Cap width - 1.0625
Outside Snap rings
1330 Dimensions: 2nd version
Overal width - 3.625
Cap width - 1.125
Outside Snap rings
S44 R3 Dimensions:
Overal width - 3.625
Cap width - 1.125
Inside C-clips
1350 dimensions:
Overal width - 3.625
Cap width - 1.188
Outside Snap rings
