It's hard to say based on this information alone. You could possibly have our 39-017, but you will have to carefully compare the specs we show to your own hardware to be sure. The installation screw would be our 33-081. If this isn't a match, you will need to remove your operator from the window and take a few pictures of it for me to see.
