i bought a set of pats quick change ends for my 4240 that has the sliding ends and they look great except one problem. the hole in pats quick change ends that the pin goes through (the original pin that holds the sliders in the 3pt arm) seems to be about .100" too big and has alot of slop is that normal and ok to use or should i have the hole made smaller. the pin dia is 5/8 (.625) the hole in pats ends are .810 should be .750 or 3/4 in my opinion. has everyone just used them as is ?
