I had also posted that fact but I was just passing along info that I had read years ago. For some reason, some people don't like the Poly bushings in the LCA because they don't possitivley "lock" the pin in place or something like that. I don't know where the LCA would go though. It's held in with the strut rods and the torsion bars. You can do what ever you want. Personally I went with the OE bushings in my LCA's and Poly everywhere else. I've heard that the ride is a little better doing it that way but who really knows for sure.
