Yes, thanks for the response. The Land Rover service manual showed the same style pin (non bushing) in both locations but the notes below referenced putting the bushing pin in the bottom location.
Hopefully my brake job works. I had 0.001 lateral run out on the disc before I put the caliper on. If these discs warp (or begin to have thickness variability) I will be at my wits end. The bushing pins are a little more sticky than the regular pin so I hop the source of my problems are not the bushing pin.
