My Repair & Advice
First I had saved the metal pivot brackets and springs from the old piece, I remounted them on the new frame and carefully installed the 2 tension springs. After that was done I carefully installed the new completed vent cover by first positioning it to the left, in place then carefully sliding it to the right. All that holds it in place is 2 screws on the top of the micro.
