my question is why are you interested in this change? is the 3 speed bad? are you having trouble with the column shifter? do you think the 4 speed will improve something else?

Generally I just prefer floor shifters over column (just what I'm used to). The three speed works, but the column pieces are very loose and flopping all over (I know I could replace these). The previous owner tried to modify the column shift somehow and botched the job (not quite sure what he was doing).
I figured if I had the 4-speed available, and it was a relatively easy swap, I would just switch them out. I'm not looking for any performance gains or anything like that.
