I'm looking to shift my own gears in my malibu and I've been looking at different transmission's to use. I've looked into the T5, TKO and T56 going into a Gbody but I've never heard of anyone using the nv3500. I think they used it in S10's so I'm guessing it should fit. The nv3500 also came in bigger trucks so it has to be tougher.
