well, per quick research it looks like the V1 hubs bolt right in so i'm not entirely sure why we're making it so hard to modify a hub in order to be 6x115 when the stock ones work just fine...
both bolt circle diameters on the inside are 4.567" and 3 hole...so they bolt up. the differences are the speed/ABS sensor (V2 doesn't have it), the bolt pattern for the wheels (5x120 vs 5x115), and the studs being 14mm instead of 12mm.

Might be able to find the specs through http://www.skfpartsinfo.com/. Unfortunately, that site doesn't want to work properly on the Navy network here at work, so I can't look anything up.

this means 04-07 base CTS hubs get you 5x115, C5 vette hubs get you 5x120(.65), or V1 hubs get you 6x115. all bolt in and function properly. it'd just depend on what you want for your bolt pattern.

Maybe im looking at it wrong on the (info) from rock auto.....but it looks like the 3bolt circle is off by .060"....between the 2nd gen stuff and the first Gen.
Bolt circle H....

that's the exact same argument people have with 5x4.5/115 and 5x4.75/120. it'll bolt up and work fine unless you are an engineer and need it to be exact to make sure you can sleep at night. the tolerances aren't tight enough to hold those values as exact. they might not bolt up if you just so happen to have two pieces that are on opposite ends of the tolerances, but that's about it.
the holes in the spindle are through holes. they can be misshapen all they want.

If you want to do this swap and go 5x4.75 DSS makes a custom 33 spline Corvette hub that will work.
V1 hubs will not work they are only 30 spline and V2 hubs do not have the wheel speed sensors.

But if you're starting with a V6 2nd gen rear assembly (which is what the OP did), then the axles appear to be 30 spline, so they should work with any of the hub options that Bio248 mentioned.

LSX416 started with a base cradle and suspension....then switched to v2 diff and axles...the V2 outer CVs are 33 spline......so he used the Aztec front hub/bearing with 33 splines and matching (V1) ABS sensor. (Note: the inner stub that goes into the diff is different between Base2 and V2, strangely the V2 stub is much cheaper).

then the aztec hub is what you want. there'd be no off the shelf way to get to 5x120 unless you did what was said above with the special DSS hubs, but 5x115 is better anyway.
that hub is the same that's used across a variety of 5x115 cars (grand prix, regal, aztec, deville, intrigue, etc.).

I looked at the SKF site from home and I didn't see a rear hub listed for the V2. However, the front and rear should be the same, and the specs for the front hub (BR930555) showed 33 splines.

You could use a base diff and axles.....you'd be at 30 spline.
A base cradles with 3.73 easier to find than v2 manual diff.....I think that most or maybe even all 3.73 base models have LSD (G80)....but j can't really confirm.

So would this be a better route to go over the 8.8? besides the gear ratios, I am just wondering if it can hold power like the 8.8 can. I like the idea of it being cheaper, but sometimes that isn't always better. Hope to see a parts list.

In my opinion, your best bet is to do a GeForce 9" IRS with the dual-mount V2 housing and V2 subframe. When they have their holiday sales, the prices are comparable to CS's 8.8" kit.
