Looks like you have quite abit of time into figuring it out. You might look at the below thread for a fix that many on the forum are using. I made my own, but bought one for a friend and he is REALLY happy with it. The problem is after you fix one spot you will have another. Now I have air come thru the slit for the tilt steering but nothing like the shifter.
This seems to work very well. No holes to drill. I used the existing bolt holes and converted to studs. I will see what more will cost I paid $125.00 with computer time. I think a duplicate will be $75. I do have more rubber I will donate
