Box at end of steering column

The Chrysler box coupling has a cap that is somewhat "bottle cap" crimped in place. I do as little distortion as possible to remove it ( like a bottle opener does ) so I can reuse it / put it back again. Yes the coupling rebuild kit includes a new cap but... its just a flat piece cut out. Recreating the crimp so it stays in place is nearly impossible. Many who have tried end up buying the additional formed wire retainer from aftermarket.... Rare Mopar 2996935 Steering Coupler Retaining Clamp - most Dodge Plymouth | eBay
The cross pin in the end of the steering shaft is a very tight press fit and must be centered. If the original isn't severely worn, leave it be. If you do need to replace it, find a press. Getting it centered with the BFH is another nearly impossible task.
