Another auto-to-manual swap

My stock A-904 has started slipping and I'm sick of driving cars with automatic transmission so I'm thinking of converting my car to a 4-speed. I searched for other threads about conversion to manual, but I want to know what parts I will need and how much it will cost if I use a hydraulic clutch setup (the fab'd one using OEM import truck parts) and aftermarket clutch (McLeod, Centerforce, etc.). My car is currently column-shift, will I need a different column or can I just modify this one? I've heard of the crank needing to be modified on auto-trans cars as well, does anybody have any pics of what it should look like to accept a manual trans input shaft? And I want to go with a non-OD A-833; how much do those usually cost for the core + rebuild (or an already-working trans)? I know I will have to lose the 7 1/4" rear and in the process upgrade to BBP but that's something else.
