Rubber piece at rear end of sunroof frame/trim

[Bremar 2]

Hi, I had to remove the trim around the factory sunroof. At the rear ends  of each side piece there is a thick rubber/frame sealant lump. Please see photo attached.
Is this an actual moulded item or just the final form of a sealant used at the ends of the runners. 
any help would be appreciated 

thank you Bremsr

Thanks Leslie, 

I’ve done some YouTube videos of stuff I’ve done on my 1993 Gentry.
I haven’t put them up yet because my son is still editing them but would you give permission for me to use your photo as an example of what the bump stop should look like. 
Thanks Bremar.
