    For sale is a Factory Replica of the M22 1968-74 CLOSE Ratio Muncie Rock Crusher
    Four Speed Transmission typically used in High Performance 1970 thru 1974 Corvette`s, Camaros, Chevelles, Nova`s, El Camino`s, Impala`s,
    Oldsmobile's
    and Pontiacs.
    Unlike some Rock Crushers offered for sale on
    eBay
    this transmission has all new gears. Why would anyone pay hundreds of dollars more for a transmission with used gears?
    Also included are Hand Fitted Synchronizer Sliders and Hubs. The hand fitted sliders/hubs
    improves shifting quality through all RPM ranges.
    This transmission will also fit all 57 thru 74 GM products and
    is a rare opportunity to own a virtually brand new infamous M-22 CLOSE Ratio Rock Crusher Transmission.
    The Case Assembly consists of a 1968 thru 1974  3925660 Case with No Vin or Date code. The Case also includes a 1" Steel Countershaft bushing. Side Cover 3952648 and an Auto Gear Passenger Side Speedo 32
    Spline Tailhousing.
    DO NOT purchase a transmission without French Locks on the front bearing retainer, there is a good chance the bearing retainer will loosen from throw out bearing vibration, only GM type French Locks on my Transmissions!
    DO NOT  purchase an M22 without a drain plug, you will have no way to effectively remove all of the gear lube including metallic particles that will continue to circulate and eventually lead to premature failure.
    Buy with
    confidence from a seller that works very hard to maintain feedback satisfaction. Be sure to read my Feedback comments prior to purchasing any Transmission.
