NV4500 would be a good option. 5 speed, still has a 5.61 granny low (6.34 if you grab a 93-94 model), and .73 overdrive. They came in 1993-2007 GM trucks (and Dodges).

In your case, you'd need to buy an advance adapters bell housing to run the mechanical clutch linkage. Advance Adapters has a lot of info about them on their page, along with adapters for putting a t-case behind them.
