I bought the parts manual CD from ebay (holy **** 2347 pages of everything , it is awesome).

and the only reason I bought it for was to find out if GM still sells PRE-BENT rear axle lines for a disc rear end. so I have the numbers now and I looked them up at www.gmpartsdirect.com , but it doesn't really say if they're pre-bent or not.

anybody knows ?

I can't find a number for my local gm dealership otherwise I would give them a call and ask but I have a feeling they would look it up in the same database and wouldn't know either, lol
