Where can I find correct LCA Bump Stops? Don't tell me CHINA!

The bolt/stud is turning IN the rubber, I can hold the rubber all day long and it won't tighten up. I could try the plain nut and lock washer but the rubber still might turn because there is no positive connection from the bolt/stud to the rubber part. Is that clearer?
I don't know the part number on the strut rod bushings but I think the blunt tool pushing around the ridge should get them in, I was close with what I was doing, but couldn't get that last little bit to go in.
