parts for traco double hung and slider windows

I am afraid I am having a hard time visualizing the part being described. Could we have you upload an image or two of the hardware in question? With images we can determine whether or not we can offer an alternative. 

Hello there.  am not certain about the identity of either the weep hole or your top covers. I'm forwarding this discussion to one of my senior colleagues, and we'll get back to you as soon as we can with more information. Many thanks for your patience. 

For your Weep Hole Cover, I want you take a look at our 26-186. I like this cover because it can cover a wide variety of weep holes; you'd just need to drill new holes to install it. Take a look and see if you think it could work for you. The other parts appear to be old sash levers, connected to internal tilt latches. I'm afraid we can't replace these; but you may be able to convert to surface mount tilt latches like our 26-228 and 26-229. See the video below for details.
