Ok, lets try and straighten out some rearend myths here.
1.) There are 3 different rearend widths available for the S10. Narrowest is the 2wd, the std 4wd is 4" wider, and the ZR2 is 4" wider still (8" wider than 2wd). So, for the guy in question, unless he's currently using 2" thick spacers, he'll want a 2wd width rearend.
2.) Most Blazers and S10s have the 7.5 / 7.625" rear, relatively few have the 8.5" 10-bolt, so they're a bit more $$$.
3.) From what I understand, only 4.3 V6 5speed trucks got the 8.5" rear (starting in like '97 or '98), and it was available in all 3 widths (2wd, 4wd, ZR2). If you look hard enough, you can even find factory disk brake equipped 8.5" rears with posi / limited slip.
4.) Certain special models (like the Bravada) always have posi / limited slip.
For all other applications, posi / limited slip is an option and is dependent upon what the original purchaser / dealership ordered.
5.) (Warning - Opinion) The GM posi / limited slip that is installed in these rearends (both 7.5 / 7.625" and the 8.5" rears) is a complete POS. Its called an Eaton Gov-Loc, is weak, and has been known to grenade and wipe out otherwise good rearends. It is activated by a difference in axleshaft rpms (one has to be spinning faster than the other by about 100rpm), which means its more of a limited spin than a limited slip. And, once you're going faster than 25mph and let off the throttle, it disengages (so if you're cruising along at 30mph and nail the throttle (with enough hp), you get 1 wheel peel). Not the best situation, in my opinion.
6.) I think (but am not sure about) the Xtremes got the 8.5" rear axle. Would certainly be wise to identify it for certain.
There is at least 1 very informative post on BlazinLow.com that has information on how to differentiate between the 7.5 "/ 7.625" and 8.5" 10-bolts. You might check it out.

If you are not running emissions controls, then you can plug it up.
Yes, the truck intake fits under and S-10 hood:

Edit- found it in this thread
Are you looking for a 8.5"? I gave up on mine so I just got an 8.5 out of a '95 Silverado and I'm gonna put new tubes on it and rebuild the rest.
