Why bother making this to fit stock rubber or over the counter poly bushings. Firm Feel/Just Suspension allready sells one?
How about making one to take a very high load spherical bearing. A plain bearing (poly) doesn't really technically work as the path of the LCA is not perfectly up and down due to the strut rod. There is an off the shelf low angle spherical that comes close to fitting that stock pin I.D. and LCA O.D. I found. ;)
That would be a NEW part that would take this to the next level.
They do offer something like that for the drag guys, but it's big bucks. And IIRC, it's a plain one axis bearing.... So you could sell it to the drag guys too.
