Keep in mind you won't be able to use most of the parts in the kit Rick posted. Your coupler is a completely different shape. I went through the same thing on the couple on my '66 Dart.
Here's the statement about the kit on their website: "Steering Column Knuckle Kit All Makes. Technically for the 1967 and newer columns, but we have used them for earlier cars with no issues or problems. 63 -79 - All Mopar -"
I'm guessing the shoes are shot, so if those parts fit I think I'll be OK.
