I have a 29 Fordor. I'm 6` 4" and it was too crowded to be safe driving. I made myself some new brackets where the seat back fastens to the door post, unscrewed the seat base, and moved it back 3 inched. Screwed the seat back down to the floor and fastened the new Z brackets to the doorpost. Covered them with seat fabric for looks. Lots of room now. Shifter was still in the way so I stopped along the road, reached into the base with both hands and bent it to the right. I now have a car that I can easily get in/out of, and drive comfortably and safely. Still lots of room in the back seat too.
