the operator arms are 4 1/2" from the wood frame to the joint and the other piece is 5 11/16. The restraining arm is 7". I need this hardware and anything else you would recommend for one left hand window and one right hand.

Thank you for posting! Take a look at our 39-175 & 39-176 Pella Sash Crank Operators. These look pretty close to your own hardware, but compare them and see what you think.
