I purchased the sash dyad crank 5" (39-187 and 39-188) in White. Everything fit perfect except the part of the arm that connects to the window is just a little to large which is stopping the windows from closing all the way. It is almost like it wont swing in. Your arms measure 5" but when I measured my old one the arm is only about 4 and 1/4". Do you have anything that will fit or any ideas on how I can make the adjustments to make the arms I purchased fit?
Thank you,
Tom
