  • NOTE1: Part # C241618 does not come with a gasket or hardware.

One of the rarest, yet "cool" options for the 1970-72 4-4-2's was the W-27 aluminum differential cover option. It held more fluid and was made of aluminum, so it kept the rear gear oil cooler, thereby increasing gear and Posi-life. OPGI is offering two versions of this cover that fit the 1970-72 10-bolt Olds rear end and the 12-bolt heavy rear end. These are top-quality duplicates of the original W-27 rear covers.
