Bed Slide for Palomino Real-Lite 1002

I purchased a pop-up last summer and am taking on the task of rebuilding / fixing it over the winter this year after using it for a year and seeing where the improvements can be made. It needs a complete rebuild of the roof and a few smaller things elsewhere but is in good shape otherwise.

One of the items I want to replace are the bedslides for one bed. They are both bent at the end to the point where it's a significant effort to pull it out however I can't find them anywhere.

Does anyone know where to find 68" bedslides (preferrably in Canada)?

Alternatively is there a way to bend them straight without kinking or breaking them?
