These are the impossible to find "C" clips that hold the clutch release bearing collar to the clutch fork for the 1949-64 Oldsmobile & 1949-54 Cadillac. To make it easy to purchase you can go directly to the website. I started making these clips as I needed some for a project and could not find them anywhere. Now you can have them too. https://www.kmaerospace.com/Olds.shtml
