Johnny-Longtorso : So how does one go about buying one of these mythical beasts? Is this a dealer purchase? I suppose it's a bit ambitious to ask for GM part numbers (for a 3.91 loaded unit)?
Pick the parts source of your choice; dealer, ebay, salvage yard, etc, and look for a replacement drive axle for one of the listed vehicles with the ratio that you want. The dealer would be the easiest as well as the most expensive.

Does anyone know where a 2.73 Getrag 645 might be found? Done some searching but the 3.23 is the lowest ratio I can find.

I wish I understood this. Yeah, I know that's a hell of a low ratio, it was just an idea and I figured I could swap it, see how it worked, and if the accel tradeoff wasn't worth it just sell it again :P but it looks like I'm going with the 3.23.
