I made a very good center floor shifter using a used B+M 3 speed shifter that performed flawlessly for 14 or so years in a daily driver only vehicle. I finally went back to a column shifter using heim joints that works easier than a floor shifter. I made my own rods and used the heim joints to upgrade from a 90 degree angled rod into a wallowed out hole. My upgrade on the column is the simplest solution and I have decreased the throw as well. I'll post pictures of the floor conversion if you are interested.
