I made a paper template of the belly skin and indicated about where the holes go, then I printed the template out of the 2006 Q3 issue of Beartracks. I glued two copies to an old file folder and cut them out. Come to find out that the hole needs a bit more side clearance, so I added 1/8th in on both sides. Once I figure out how the panels will have to go on and off with the gear installed, the holes will probably have to be widened or elongated.
