1989 Pontiac Turbo Trans Am Coolant Reservoir Blanket. This is a high quality replacement part that is an excellent item to use to replace a worn unit, or for a show, or as a spare to keep on the shelf. I have a limited number of these remaining and when they are gone they are gone. These fit the coolant overflow tank for the 1989 20th Anniversary Turbo Trans Am and I do not know if they fit others. Very well reviewed product by TTA owners.
