The way your rear-end will be setup, the pinion will be in the same location as it would be with the factory GM rear. This means that the housing will be skewed off-center slightly to allow that placement. This is one of the reasons I decided to do a 12 bolt with Torino housing ends instead of a 9".
That said, the only time you're really going to run into any clearance issues with a 9" (or 12 bolt) is if you're trying to still use a factory style transverse muffler. If your exhaust system currently uses under the floor mufflers which is more typical of aftermarket stuff, you won't have an issue other than the fact that you'll have the housing off-center by a couple issues and one axle tube (and axle) will necessarily be longer than the other.

I thank you...I think this makes sense now. If I were to have them center the housing then the drive shaft would be at a greater angle (left/right) running through the tunnel and even closer to it at the rear. I imagine the extra angle is less than desirable as well?
My exhaust is going to another project maybe next year. It will need to be a custom thing anyways because of the bracing and trans cross-member changes. Being 2-3 inches off center shouldn't be too terribly objectionable from a visual standpoint (I hope). I've seen them in F-bodies before and never noticed. I just wanted to be sure this was a normal situation before I place the order.
I thank you gentlemen. The people on this forum are truly great.
