Plastic Guides for unknown brand windows

There is no identification on the windows as to the Manufacturer and have no idea when these windows were installed. Purchased the house in 2006. Took one of the broken
guides off and the only ID is a patent #, 3444648 labeled L or R depending on which
side they were removed from. Might as well replace all of them down the road which
entails about 68 pcs. give or take. May need other hardware down the road but would
like to get started on this project after the first of the year. Have similar windows
on the front of the house but metal hooks, no guides. Would appreciate the help as
we can do some serious business next year.

Thanks,
John

P.S. The house was built in 1973 with a screened in patio, no windows in the back.

Dave,

Perfect! Everything I need is posted. I plan to get started on this project after the 1st of the year. Will
order the replacement hardware pending final inspection.

Nice to find an expert that knows what he is talking about.
Thank you for the enclosed pictures.

Hello Dave,

Spoke with you about 5 yrs ago and you put me in the right direction. Had to get some other projects out of the way but I'm ready to start working on the windows, one at a time. Please note my private email address that I only give out to trusted sites. That being said, find new enclosed pictures pertaining to above. Purchased the rivet tool as per your advice. I will need all the hardware along with the replacement parts. Don't need all of them just yet but will order as needed along the way.
Question, do you carry a kit with the hardware and parts needed for each window?

Thank you,
John
