You won't worry about dropping or losing any parts with these hood pins! The spring loaded clevis pins always stay attached to the aluminum retainer plates, which get riveted or screwed to the hood surface. The 7/16 inch diameter aluminum hood pins measure 4 1/2 inches from the clevis pin opening to the bottom of the pin, and are easily shortened if needed. The clevis pins are a full 1/4 inch diameter for strength. Blue anodized aluminum hood pins and clevis retainers; silver zinc plated clevis pins and hardware. Sold in pairs.
