You will probably need to fabricate a new shift rod that goes from the bottom of the shifter to the transmission. The lever arm coming out of the C-4 should be for a floor shift model to make this easier, but if its from a column shift model you can also fabricate a bracket that bolts to the existing lever arm, and repositions the point where the floor shift rod attaches. If I recall correctly I did that once, and had to space out the neutral safety switch a bit to make everything fit. Not that tough of a project...
