OK- I put my Momo air race leather shifter on tonight and to my disgust, found that the leather boot no longer stays where it should- OK, fine- Tim Taylor time, right?
So I went in the house looking for what would work to make the boot stay in place- and here's what I did:
Take a plastic bottle cap and a kitchen knife, slice the top of the cap in a cross formation- then push the bottle cap over the shift rod (console off), thread side (of the bottle cap) down. Now replace the console and put the shift knob on. You can feel the bottle cap through the leather boot and adjust the height of the boot to the bottom of the shift knob. Voila! No el cheapo looking saggy boot to go with your new shift knob.
Anyway, I'm sure you guys have come up with other solutions like tie straps, but maybe this will help someone else out anyway.
