    Here is some info from Marlin Crawler:

    How to ID Gear Drive Case


    If you have 7 bolts in the rear cover then you have the gear driven unit.
    If you have 5 bolts holding the rear cover then you have the chain drive unit.
    Bolt #7 is behind the drive shaft and can't be seen in this picture.

    You should be a driver side drop, correct?
    If that is the original T-case, it probably has a chain driven case. That being the case, there may be a other issues to check out... possibly the 3rd member or ring & pinion.

    Does it whine while you are off the throttle, in gear & coasting?

    OK, perhaps there is an issue inside.

    I have an extra if you want it... just cover shipping.

    Oh, and that is a chain driven case.

    Ist gens came with the chain driven case. The gear driven units are an older version. Mine is a gear driven Inch Worm 4.7 T-case.
    As to which are better, don't know but I'm sure there is some debate about them.

    It's not a J shift case but you can work with it to make it so with the parts you have.
    At least the insides are good, no whine.

    Does it sound like a manual trans car in reverse while in 4lo? If so that whining noise is normal.

    That's only a problem if you have duals, the op doesn't have duals. Completely different problem.

    Yes sir... I was more after the noise portion for the OP. Guess I should have made that clear.
