77 280z. Rear hatch side bracket has this brown, cork material. Is that oem material that has eroded since 77 or is that bushing material?

I would. At least contact 240zrubberparts and see if he can make a set for you. He lists "Out of stock" a lot, but will make things if requested. 

They hold the spring in place and act as a stopper for the white plastic slide piece. The little feet on the sides hold them in and often break off. Used ones like CO's eBay set would also be a way to go.

I might even have an extra set. 

great idea with the rubber part which would probably last longer too.  Sent you a DM.
