Rubber block between frame and control arm

[Mracer71]

What is it called - the rubber block (almost want to say bump stop) that's attached to the frame right above the control arm? It got brittle and fell of so i am looking to get a replacement. Any idea?
Thank you all.

I have used this website several times.. They carry a complete catalog for the late model Chevy's.
