Do you camp? Do you mind a rather redneck solution? Are you sitting down?
Y'know those 1-lb propane cylinders used for camp stoves (or, alternately, the taller skinnier ones used for torches)? Take the cap from one of those, and reduce the "height" by about 1/3 with a pair of scissors. You may have to trim off more, closer to 1/2 the height. Put a small piece of double-face tape on the underside, and press onto the shifter. Put a black zip-tie around the outside and tighten moderately, and cut the excess. It's actually quite inconspicuous; you have to look closely to see what it actually is. If I think of it, I'll post pics of such a repair tonight.
