Review on Windshield Washer Fluid Reservoir Cap for Buick, Cadillac, Chevy, GMC, Chevrolet Models (Excludes Other Vehicle Makes) by Matthew Guiney

I got the gas cap and DEF caps and installed them and they fit, but after one ride I found the gas cap difficult to remove with my old arthritic fingers so I got a drawer pull, through drilled the lid and attached a pull rod to the lid to have something else to grab when removing. I also put a light coat of plumber's grease on the o-ring to make it easier to remove. Now it's easier to remove the cover.
