I am still not sure what bellcrank you are referring to. I need pictures, because I may not reference to the same part you are looking for.
I do not have any rubber ends for the cargo cover. One of mine is missing an end just like yours. They are harder to find than the cargo cover itself. Hardware stores have ends for table legs, and rod ends rather cheap, that could be used in place of the OEM ends. If you put them on both ends, no one would know the difference.
I am going to the yard today, and if you want to send me a picture, my phone number is 727-692-5510. My phone screen is fairly small, so make it fill the screen as much as possible.
