D17 lift arms too high?

D17 Series 3...Have a three point conversion on it, and can't get arms low enough for a dirt swoop bucket I borrowed from a friend without leveler screwing out.  When the lift is all the way up, the arms are almost pointed to the sky.  I was wondering if I could remove the snap ring, pull the arms off and reinstall them one spline lower, or is there a groove that prevents this.  I'm thinking someone raised the arms in the past.  Any advice appreciated,,,   Thanks in advance, Andy

Thanks, Alvin.... With that encouragement I went out and tried it,,,as they say easy peasy...hardest part was reinstalling the snap rings without proper tools. Still points pretty high when raised completely, but lowered, much lower, should work.  Soon as I cool off (hot down here in Oklahoma) gonna go try it out....  Again, thanks    Andy
