Your C3 & C4 Corvette driver and passenger windows can rattle, leak air at speed, and even become scratched. How? Over time, your factory anti-rattle bumpers harden, attract dirt, and deteriorate with age. Eckler's 1969-1996 Corvette anti-rattle door window bumpers are high quality duplicates of the original GM parts. They fit just like the original anti-rattle bumpers but with exceptional durability thanks to modern materials and manufacturing methods and protective felt lining. These are sold as a complete car set with hardware.
