I took a 80MB Prodrive ELS apart, and its rubber crash stopper is on the bottom under the platter.

So, I removed the head actuator assembly, Since it was a single platter drive it made things much easier. Removed the platter, etc.. carefully.

Took some goo gone and got rid of all that rubber. Used various layers of heatsrink to replace it. Its a bit harder, but its better than nothing at all. Re-assembled and to my surprise, the drive worked perfectly.

now THAT was nuts. I never rebuilt a drive down to that degree before. I will have to do a video on my next drive. i have 1 more ELS 80mb left which should be the same as well.
