I think your 39-264 will work to replace these, how do I determine if I need the adapter plate? For your part, the outer screw holes are 3 11/16 inches apart, mine is about 4 3/4 inches apart, does that matter?
thanks

I agree, the 39-264 looks good. The adapter plate is used with older windows made from 1995 to 1998.
