This might have been posted before, but for those that are getting G0704 delivered now, the bolts that come with the unit do not have to be ground down. The opening that the bolts pass through is now large enough to get them through.
Just thought I would share in case this was a recent change.
Same with my mill I took delivery on back in Feb last year. I just did the 3 bolt mod and discovered the same thing. Meant to post, thanks!
