Cool. I was mistaken about the additional materials for that second bushing option I posted above. The Delrin and Teflon are available for an adjacent bushing which I dont think is applicable for us. I ordered the same material you used(MDS-filled nylon) but 4 of the 3/4" bushings for the u-joint and 2 of the 1/2" bushings for the shifter itself.

I also ordered a second Subaru oem shoulder bolt(cause it has that unique and near perfect shoulder length) to use where I removed the riveted pin. I am convinced clearance isnt gonna be a prob or at minimum a little grinder work on the tip of the shoulder bolt. Ill post up pics when the parts get here.
