Dewalt drill with a 1.5" diameter hole saw. Then if you are completely anal, you can hit the holes with a portable propane torch to melt off the fibers. Works well, I have done it to my 2 previous sled before the factory started doing it.
You can make a template out of a 2x2 then simply set it in the lugs c-clamp it and drill away. I typicaly only dril (3) holes between the drivers on each lug, however some drill (5) all the way across. I thought the track was a little week when sidehilling when the area outside of the drivers was ported. Just my $0.02
Thanks so much for all the responses. I do have all the equipment so i'll probaby just get to it. Thanks for all the responses and when the time comes i'll probably have to post somemore Qs.
