Yep.. Lost the one from my ashtray about 3 weeks ago..
Had resigned myself to the fact that my cover would be like a mouse trap forevermore..
It was jamming as you mentioned, and I guess I had a missing tooth.
When I started taking things apart (in a manner that I thought was gentle), next thing I heard was the wheel falling into the depths of the console..
Are you thinking of getting a pack and then selling a few off as spares??
I presume they come in a pack of something like a pack of 10..
If you are, count me in..
