Scary steering shaft/coupler failure!

I bought the entire rebuild kit from Detroit Muscle Technologies (DMT). A little pricey, but includes everything you need, including the retainer. Then I bought separately the lower steering column seal for the 66.

Here's the kit. Mopar A B E Body 66-72 Steering Column & Coupler Rebuild Kit

I'm not a huge fan of the retainer, but safety first!! Glad you made it home safely.
