Yes, the assembled length should be 6-11/16". The factory makes a special tool for pushing out the "O" ring retainer. Of course the shift rod must be removed.
Frank Robb makes a duplicate of this tool for those that can’t afford the factory price or where with all to make there own. The alternative is to tap threads into the top of the retainer and pull it out with a long machine screw.
