This a BRAND NEW SUPERCASE M22 Muncie Rockcrusher Style Transmission. This is a BEEFY version of the original Rock Crusher transmission. Most all the weak points of an original Muncie have been solved by the Super-Case design. The Supercase has extra casting in all the known weak areas. The mid plate is aircraft grade aluminum. The tail housing has also been beefed up. Each new SuperCase transmission is built from the highest quality available. Includes all the goodies: SuperCase, gear ratio choice, heavy-duty set with a oilite bushed side cover. Ready to be filled, install and it's available at a great price.

New THRUST BUTTON Super Case included!

Complete New M22 SuperCase Transimissions include legendary Italian gears and shafts by Masiero, synchronizers by Euroricambi and Auto Gear's own thrust-button SuperCase, aircraft grade aluminum, 'Oilite'-bushed shift cover, improved tailhousing and investment-cast steel shift forks. Correct fit for all 1969 - 1973 model Camaros. Gearboxes come packed in a custom wooden crate.
