Cranking mechanism housing pulls away from window when cranked

Hi, My cranking mechanism pulls away from the window when cranking. The 2 screws (that hold the cranking mechanism to the window), when tightened, do not hold the mechanism any more. the screws do not seem stripped, but perhaps the housing for the screws are stripped? What's the best fix - new longer screws? or new mechanism?

Your hardware looks just like either our 39-139 and 39-138 operators, or the 39-141 and 39-142. It depends on the length of the link arm, so please compare and let me know if either set matches up. That said though there is but one key difference between these sets of operators and your old hardware. It looks like you have reverse mounted installation screws. With that in mind, you will also need our 33-205 threaded nut to reverse install the installation screws. I've installed these with the help of a bench vise; you just press them into the holes at the front of the operator base. Let me know what you think.
