Window Lift Rail Endcaps?

A home owner from Ohio says:

Hello,

Were going to clean/restore these windows in our new house. They are overall in good shape but these end caps have yellowed while the rest of the window is white. I can't seem to find any kind of replacement part for these end caps. Hopefully we're not forced to try and paint them.

Thanks in advance.

Hello,

Take a look at our 26-051 end cap. I believe this is the part you are looking for. See if they match up to yours. These are no longer manufactured so we only have the beige color left in stock. Thanks for posting!
