Tom, Sounds like you will have plug the old holes, presumably with epoxy, then drill the new holes. At that point you will have to consider how to seal the core at the new holes. Why not not just over size the existing holes, fill with epoxy and then redrill to mount the new track? I believe you said the holes were about offset by 1/16" difference. Not sure what the cumulative "creep" would be over the length of the track, you may have to drill out a 3/4" hole to pot up with epoxy. Only drill to the bottom skin, then there will just be the existing hole going through (1/4"?). Tape the bottom, fill with resin and then drill your new holes in the epoxy. Use a good backing plate below. A piece of flat 1/8" x 3 or 4"aluminum stock, or plywood. (check your bolt length when looking at the ply thickness) Take pictures!!

Thanks to all of you with comments about car and track setups. As always you came up with several good approaches to the same end, and I will have to decide which is best. Since my track placement does not seem too bad, I might consider buying a slightly longer section of track than necessary, and cutting it so the new holes fall between the old ones, which can be plugged with epoxy.
