98 passat window regulator plastic piece

I have a 98 passat and the plastic piece that holds the window on the regulator broke off of both front windows. So now I have coat hangers holding up the windows. Does anybody know where I can buy just the plastic pieces that bolt on to the bottom of the windows? Actually they fit onto a piece of metal(bracket) that bolts onto the bottom of the window.
Thanks in advance for all your help!!!!

you unfortunately need to buy new window regulators for both sides at about 160.00/ side.
