Slipstream

I just completed installation of this mount on my 2000 Sport. I was able to pass the nut and appropriately sized plastic nut holder up through the bottom of the stem tube. To do this, I taped the nut into the plastic nut holder, and pushed the assembly up to engage the ss mounting screw using a socket with a washer taped over it to provide a flat surface and a series of 1/4" drive extensions. This allowed me to leave the chrome top nut torqued in place. I used a small piece of rubber tubing to support the ss screw where it passes through the chrome nut hex hole, and used the kit supplied rubber expansion plug in the stem. I did trim the actual mount base (as in Swooshdave's photo earlier in this thread) using an angle grinder with a cutoff wheel, a file to clean up the cut, and some flat black spray paint to protect the bare metal. I also put a locally sourced neoprene washer between the mount and the chrome nut. I hope this helps... Now to mount a USB outlet somewhere nearby in order to power my phone/gps.
