yeah, I bought this kit from eBay :
http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWNX%3AIT 4.11, limited slip setup. And I got in some 6 lug 30 spline axles from ECE. I also had to buy a new 30 spline yoke, got it from Summit for about $65.
I was just expecting this rear end to already be 30 spline, and not 17 .. that got me thinking that this isn't the original.
