1991 FLT Swingarm Rubber Isolators

Took rear swing arm out of my 1991 FLT and I cannot tell if rubber isolators are good or not. The isolators have no tears and were creating no problems I know of. The shoulders are sloped, they are not at a 90 degree agree angle from vertical disc part were pivot shaft goes through. Are they supposed to be sloped like this or is this wear or fatique. I cannot find clear photo on net showing what they look like new. Any help appreciated. thanks, Buster

They should be "sloped".There is a small hole on one side that will index it in the correct position.There is a small pin that coincides with the hole on each support.
Hope this helps.

Thanks for the info, Buster
