I purchased a 1989 Toyota Odyssey, that runs great, but needs some weather proofing work. I'm looking for a supplier where i can purchase the rubber beading that hold the glass in place. the previous owner had caulked all the areas where the beading had shrunk, but it still leaks. Also I need the small plastic weep hole covers that are located in the bottom of each window unit. any help in these areas would be greatly appreciated. thanks,
