Hoping to restore my awning windows

Hey there, Dick. Thanks for contacting us. I'll do my best to help you with this project. 

First, I believe you have a VE Anderson brand awning window. That helpfully narrows down the list of replacement hardware by quite a bit, though some parts aren't made anymore. Keep that in mind as we go forward. 

Starting with the vent hinges, the ones you show look like our 39-539. Your operators would match our 39-259 and 39-258. Look over our photos and dimensions to confirm, but I feel confident that these will match. 

As for the bushings, we unfortunately do not carry a replacement and I'm not sure if yours are even still available. Take a look at the various type of bushings and guides we carry to see if you could adapt any to work,  like our 33-206, 36-077, or 36-084. If your bushings are not worn I highly recommend trying to reuse them. 

As for the rivets, what I have done for repairs was to use a pop rivet. The original manufacture used rivets which were installed at the factory when the window was being assembled, so they're a lot more difficult to deal with. I find that using a large pop rivet with a 3/16" diameter works well in repairing awning windows and is generally a whole lot easier.

Let me know if you have any questions.
