What are the Correct End Link Bushings Front & Rear

[Saint Bernie]

I just bought a low mileage festival car and the rear end link bushings have dried out and disintegrated - they look like crushed life savers. They look like they were origionally a cream color. AC Delco still has several listed but the Raybestos ones looked closer. I am trying to keep the casr origional so does anybody have the correct GM part#?
Thanks
Ken

The originals were a yellow color and a type of poly.
I haven't found a "correct" color replacement. 90or 91 the cars went to a blue poly.
Front and rear are the same.
