Sliding Mirrored Closet Door Track Replacement

I have a closet door with a rusted floor track. This door has rollers that hang from the top track; at the bottom, there are rectangular plastic nylon(?) tongues that snap into the grooves of the bottom track, similar to the convex rollers, but not wheels. The rack looks just like your 23-240 below - do you think it would work with these tongues? I can provide pictures id necessary.

Thanks,
Mark
