Thanks for the link...
I'm not sure that's what I would need, but maybe.
It feels to me like the black rubber strips are lose in the channels they mount in, so i think they could be slid out frpm one end and removed, then replaced without adjusting or loosening anything.
I think I'm going to try the black silicone idea this weekend, and if that works call it done... only out $6 on Amazon.
Thanks again,
John
