I ordered me a set with the group purchase at SpeedHut.com. According to the instructions they have, the dials can be put on without removing the needles. I also ordered the 220mph speedo. I was wondering if, or can it be calibrated with a yellow box or GPS, or something. Myself and others have been asking this question but to no avail. I wish that someone could or would answer this question. Usually Ninja Eater or Narcissus has some good suggestions (hint).
I did this mod, it took about 45 minutes. Take the windscreen off then the mirrors. 2 bolts and plugs and the whole gauge package is out. 7 bolts on the back 2 on the gauge itself then back together. The instructions were good.
I just did this upgrade to my 01. It wasn't hard at all. If you have a little time to turn some screws that's all it takes. I order the gauges form StreetRacerParts.com for 78.00 plus shipping. You get all four gauges and its the indiglow gauges.
Like I said very easy upgrade. If you have any question please email at firstname.lastname@example.org
