i have several replacement windows with broken pivot arms. The window locks say "Harvey" i searched your website and believe that your pivot arm product code
26-423 is the right part but would like to be sure. The window sticker(s) show the window to be a 30-01742704 CWWDH (see attached pic) or series Classic Pro-Weld DH with MST: 3050
i have not yet drilled out the rivets to see if the part remaining in the window has the little 45 degree piece as shown in your picture but the dimensions on the piece i have that broke off match your diagram dimensions.
Is this the right part?
Thank-you
