The safety check is to lift the front so the forks fully extend and make sure there is some slack left in the lines. I believe galfer has a right and left side and the left side is a tad longer. If I remember correctly the angle of the fittings on the caliper ends are different. If you get them backwards on the Gen II then you can't get the upper caliper bolt out to remove the caliper.
Just couble check to make sure the upper caliper bolt (Gen II Only) is not restricted for removal and be damn sure you have slack in the lines when the forks are fully extended or you may pay a heavy price!
