You might consider going with the Dirty Dingo mounts http://dirtydingo.com/store/product_...=1367&CDpath=8 , PN: DD-2575-4. I think you truck has the same frame as my Blazer, and if so, the extra money in these mounts will give you a lot of flexibility so that you don't have to mess with the drive shaft, rear crossmember and transmission mounts. Everyone who has used them were very happy that they did, and those who didn't said that if they could do things over, they would have used the DD mounts. I also hear 2010 Camaro exhaust manifolds or 2009 Pontiac G8 manifolds work perfectly for frame clearance. I sometimes see used sets on ebay for around $250.

What year is your 5.3?
