my '72 came w/ no centerstand. so i got one off a '74, modified the bushings to fit the '72. the mounting hole on the centerstand crosstube has been weld reinforced. it's over toward the right of the tube. i can't find where to mount the other side of the spring. searched, but most of the posts seemed to indicate it gets mounted on the left side of the cradle. i cant find anything either side. an external oil filter has been mounted and may obscure access. any help greatly apprecciated. thanx, rick
