Default 1999 Expe Rear End ID Tag Help

I am getting ready to change rear axle bearings and at least the passenger side axle. I am trying to determine which rear this is so that I can gather the parts before the truck gets torn apart.
Can anyone help me out here?
I understand that there are several different axles (spline count etc).

Here's what I THINK the numbers are:

3 S 939 A
L55 9 75 9F 18

That's a 9.75" rear, 3.55 limited slip.

Thank you!
I have been driving this truck for 100K miles. Never paid much attention to details like that. I work on my other cars, my boat, my little tractor etc but the Expy never needs much. Now its time to show it some love so I have a lot to learn.
To continue, now that I know the 9.75 by counting the bolts I see that its a 12 bolt main (?) correct? Next, from what I read, it needs 34 spline axles (?).
Feel free to let me know where I am wrong and thanks for taking the time to get me started in the right direction.

don't assume on the spline count without putting your eyes on the axle

but more than likely if the tag is still intact , it has not been opened
