The very early M20 had a smaller cluster gear shaft which was prone to failure by breaking the case the later version had a larger shaft which was fine . I destroyed an early M20 in a 67 Camaro back in the day replaced it with a M22 until I put it up for sale then I installed a later M20 the guy who bought it beat that car to death and never hurt that trans.
