When I did mine I didnt use the bumpers. Is it an aftermarket hood? All I used to hold mine up was rubber hose over the pins, cut to length. With a liftoff hood you dont really need any bumpers since theres no hinges that have to be guided in place. I'd think if you look on ebay or somewhere for pics you could find good underhood shots to see if they do look different, but like I said cant see needing them.
