Best trans for a manuel swap?

I've decided I'm going to with a manuel instead of rebuilding my 904 eventually. There's plenty of NV3500 5 speed's around me and T56's and stuff, no 833's though. The NV3500 is a truck trans though so I think the gearing wouldn't be good for a car. Any advice would be great on a route as I'm new on manuel stuff :newb: lol
