You might try rebuilding your tracks. I have found and used with great success Velcro loop. Use the self sticky stuff that comes from an upholstery supplier. It is still in place on the several cars I have done this with.

First clean out all the old material. I have found a small wire wheel does a very nice job. Use lacquer thinner to remove any glue remnants followed by a good cleaning with rubbing alcohol. Cut the Velcro into strips, lay the first in the bottom of the channel then do the sides. Any excess can be trimmed by using a razor blade and running it just under the stainless bead.
