FYI on K-frames

Stuff did fall apart back then. In the mid 70s Dodge had a problem with steering box mounts failing on the full size vans because of poor welds.

I bought a 74 B300 new and the build quality was terrible, it was a major piece of ****.
After driving it a week I took it back to the dealer with a list of about a dozen major and minor problems. One of the major problems was that the steering developed a half turn of play in it.
