10 bolt limited slip to open

[Erik the Awful]

2) I have a donor that is a 92 1/2 ton with a 6 lug 14 bolt and 3.73 for $300

It's a no-brainer.

Correct. 1500 w/F44 package gets the 9.5" 14 bolt and more spring.

OP, swap that 14 bolt over, be sure grab the u-bolt saddles, and some new u-bolts. You'll need a conversion u-joint or the driveshaft from the other truck if it's same wheelbase/transmission.

Thanks for the response Richard. Definitely seems like the 14 bolt is the popular opinion here. 2 quick questions: will the spring perches have to be moved, and will the driveshaft need to be shortened? The donor does not have the driveshaft

100% 14b SF. The donor truck is also a K series right?

Yes, but it is down to just a rolling chassis now

No donor drive shaft? You can use yours as @someotherguy pointed out.

It's been covered on this forum a bunch including u-joint part #'s. No moving of spring perches if both trucks are gmt400's. It does need to also be from a 4x4 or the width of the overall rear end will be wrong (2WD is narrower)

Hey guys, I’m back with an update on my 14 bolt swap. Everything went fine for the most part, other than having to try 3 different U joints before I got the right one. I have one big issue. This is probably my fault because I didn’t check it, but after talking to everyone on here and online, I just assumed it was a direct swap, which it pretty much was. But it is definitely narrower than my 10 bolt. My truck is 4wd and the donor truck was 4wd, but my springs now rub on my tires. Is there anything I can do? I’m running out of money and patience on this project. Thanks for the help

Only thing I can think of its a 2wd axle.

I might place a straight edge across axle hub outside flange measure to leaf springs, compare new axle to old 10 bolt.
Or measure outside axle ( wheel flange surface ) across to same other side? Then wheel spacers ?

Another vote for the 14 bolt, especially for $300.
