Designing Kitchens and Bathrooms - sliding glass doors on tub

I have sliding glass doors on my tub. They were installed by previous apt. owners. The manufacturer's name is no where to be found on the doors. On the bottom rung of the doors are two plastic gadgets that appear to guide the doors when they slide and help to assure that they don't push out. Unfortunately, they have broken and it doesn't seem like tub doors are made this way anymore and we can't get parts. Any ideas how to fix this to ensure safety and not have to buy new doors?
