just create your own
I have an old Belmonte stand, and the bumpers were falling apart, nearly not holding on at all. What I did was just wrap them in black electrical tape. Since you don't have them any more, just take an old rag, cut small strips, and wrap them around the supports. Then cover them in electrical tape. I've tried to find replacements for the pads, and I didn't find a single place that sells them.
