I did one and I believe its still out there somewhere. I hollowed out a block of 1" aluminum, with 4 bolt holes (same size and pattern as the shifter). I extended the ball by using a 1 inch long round piece of steel. I beveled the edges to get a full pen weld (note: I pre heated the steel and let it cool real slow, cause its hard.). I then shaped, the steel back to cone shape without harming the ball.
All in all, it wasn't worth it.
