    I'm pulling apart my M20 and found that the counter-shaft just fell out because of a loose fit. Also it looks like the counter gear thrust washers were spinning and gouged the inside of the case so I need to get another one. My car is somewhat stock looking with number match engine but a lot of the orig equipment is gone such as all emission hardware and it has headers etc. The old case is not a numbers matching, it's not even the correct part number for a '73 so I'm not going to repair it since a new one is close to the same money as re-bushing it.

    My question is should I get a repop, correct p/n case from Camaro Central

    or a stronger but less orig looking AutoGear Super case?

    They are both about the same money.
    Before anyone says it , yes I know it's my decision but which do you think would be more desirable from a resale standpoint?
    The engine is mildly warmed over maybe ~300-325hp, I don't drive it hard and it will never see the track.

    The New Muncie case seems to be better engineered than the old one, heck for the same money I'd go new school. Looks like they corrected any problems they found in the old case. Even if it was a bit more I'd go with the newly engineered one.

    The Autogear Muncie case was a god send to me. My old case was leaking bad at the countershaft and it had 3 mounting ears welded / repaired at one time. Also went for the roller action side cover and the steel mid plate.
