I just bought a part (below) but it does not have the piece that attaches it to the actual window. the first two pics show the part installed on the other window. The third pic shows the part that is missing. I need it by Friday to pass our home inspection!

Thanks for contacting us. I don't believe the 39-329 is the operator you need. Based on the pictures of your original part, the 39-534 is the closer match. As for the sash bracket, it looks somewhat like our 39-546 and 39-545, but these aren't often used with the 39-325. I'm not sure if they will work in your case but they appear to be the best matches we have.
