Pins and the mesh column section are there to collapse when you hit the wheel. Why the column is mounted on slider blocks are not solidly fixed. Just ask my Dad... when he ditched the Bee back when I was a kid... LOL I had to fix that mess when restoring my Bee, but we never even noticed it mind you for 40+ years until I tore the car apart. Plastic sheared, outer column collapsed and broken.
I have to ask though, what year is this column from Dana, as '68, 69, 70 B bodies are nothing but a hole drilled right through each piece that line up and get the injection of plastic, the injection you said you didn't think was correct in the previous thread. Glad you took the time to reassure yourself I wasn't blowing smoke..
