Sat in the left seat to determine stick height and orientation. Installed the side panel since there is an armrest pad to get a more accurate height. Marked the stick and cut to length. It should be almost exactly the same height as the right. Sat in the right seat and figured out orientation for that grip too. Marked the intersection of the tube and base for removal to the drill press. Taped the cut off portion of the left stick to the base of the right stick since they are the same diameter and used a straight piece of steel to mark the centerline of both sides. Started with a #30 bit and progressed to a bit and reamer fro an AN3 bolt per Vans SB. I may order a button pin fastener from McMaster-Carr to make removal easier. Marked the left stick for holes and slot for the left grip. While I was in the seat, I checked on a location for the parking brake bracket which hopefully won't interfere with my knee.
