How To A-833 4 Speed Rebuild pics

The rear center hole is drilled deeper in some transmissions. That is where the bolt with the longer shoulder goes. It is made that way to line up the side cover better. After you install the side cover "snug" the bolts up ( not to tight) and then tap lightly on the bottom of the side cover to move it up towards the top of trans. This will make it go in reverse easier and come out easier. This even helps if your trans. uses the long shoulder bolt.
