Looking for window parts

Hello, I'm looking for a few window parts and il do my best to explain what I need.
I can't find any manufacturer name on the windows anywhere but it's a manufactured home from 1999 and the windows are original.

I'm looking for tensioner or extension springs that help support the weight of lower window when pulling up on it. The Springs measure about 24" long with a diameter of ? to 7/16" wide
The springs support the lower window and it weighs close to
40lbs + or - a few pounds.
I'm also looking for weather seal strips that measure 3/16" wide with a lip on both sides and the length of bristles is ¼"
The length doesn't matter since I can cut them to size.
Any help with identifying any of these parts and ordering them for me would be greatly appreciated.
Please let me know if you would like anymore information or more pictures,
Thank you.
