The Mittler Bros. Outer Lineup Blocks (Ford / Mopar – Dana / Olds) are precision-machined round tube alignment rings used in rear-end narrowing applications. Designed for Ford 9″, Dana 44, Dana 60, Mopar, and Olds housing ends, these outer blocks slip over the jig shaft and seat against the outside of the trimmed rear-end housing to ensure accurate, square, and true reinstallation of the housing ends.
Sold as a pair, these 3.150″/2.875″ outer blocks are included in both Mittler Bros. Rear-End Narrowing Kits and are also available here separately for builders who need replacements or are assembling a custom narrowing setup. Made in the USA.
