Hi there! I am very sorry for the long wait; we appreciate your patience during an incredibly busy season.
Take a look at the 39-399, 39-429, and 39-434. Review the specifications for each and compare them with your old assemblies to confirm a good fit.
The 39-541 track slider and 39-232 folding handle are sold separately.
Please let us know if you have any questions.

Hello!
These seems to be a match. We also require the opposites for other windows. Can you send the part numbers for the opposite for 13-1/2" as well as 9-1/2"?
Thank you!
