Automatic to 360/4-speed conversion

How much time and money would the conversion cost (the manual transmission itself, linkages, shifter, clutch, etc)? I think everything needed from Brewers is the $3200.00 range very very simple to do and yes toss the damn automatic as far as you can go 3:23 or 3:55 gears if you don't want to bang the 4 speed hard you can go with the 833OD
