Automatic to 360/4-speed conversion

We converted my dads Coronet, much the same process. You will need:

Transmission floor hump and front carpet that fits it
Transmission with shifter with A-body tail
Bell Housing and throw out arm
Clutch kit
Flywheel with correct balance
pedals or at least the brake and clutch pedals
Z-bar, lineages, ball pivots and spring
Frame bracket (this weld too the frame on the inner fender to support the z bar
Possibly a drive shaft or at least a yoke if your 904

You can gut the column of the shiter suff but you will need to take it apart or find a floor shift column.
