I have spherical rod end suspension pieces on both of my Lotus and if you are using the car as a DD you don't want them.

Outstanding!
I too have issued MEYLE HD replacement parts.
Good stuff at a reasonable price.
At ~175k I have a few out these to do.

as stated I have these in my daily e34 (front UCABs) and I have no issues at all. I doubt putting these in the rear will cause any issues.

Hey OP, do you have the tool available for rent? I'd like to get myself a set of 4 and pour urethane into them as well a la your method, just don't have a line on a local tool rental.

Was wondering if I could put a flat piece of modeling clay under the bushing and place the bushing into the clay, to stay in place and also to keep the urethane from spilling out, once cured, I should be able to peel the clay away from the bottom of the cured bushing right? Should be a little bit of a more "precise mold" on the bottom as opposed to using packaging tape right?

Let me know your thoughts and if you have the tool, I'll gladly pay for the rental and insure it on the way back to you.
