8.75 rear end shocks

Lelo Dart said
Should be the same for any A body leaf spring rear end. Try some WD-40 when pushing them on. B and E body use a bolt through the top with a metal sleeve inside the bushing. The bottom mount is the same on all. As far as I know. Can you post a picture of the offending mount?

Here are the upper and lower mounts . You can see the kg5511 has the metal liner in the bushing that is the same OD as the mount itself. The picture shows a side by side of the new vs what came off. I dont think pushing the sleeve out is an option.
