Got the part on EBay - see attached link.  My husband did try to use a screwdriver but broke a small piece off.  We are going to try to heat it a bit to see if we can make it more pliable and use some silicone. 

Thanks for your comments!

Thanks, I did happen to see that on ebay. 
I think I am just going to try to repair the issue I have with mine. I am not having any luck with Cesana.
