The Mittler Bros. Dana 44 / Olds 57-64 / Chrysler 8-3/4″ Inner Puck is a precision-machined alignment puck used in rear-end narrowing applications. It slips over the Mittler Bros. 1-1/2″ jig shaft and seats inside the Dana 44 / Olds 57-64 / Chrysler 8-3/4″ bearing bore to ensure accurate, square, and true reinstallation of the housing ends after narrowing.
With a 3.265″ OD, these pucks fit the Dana 44, Olds 57-64, and Chrysler 8-3/4″ bearing bore — covering a wide range of popular rear-end housings commonly found in cars, trucks, and performance builds. Sold as a pair. Made in the USA.
