Steering Coupler 1967 Barracuda

I like the pin, not a fan of the clip. My 65 had neither and I could pull the column up 3 inches while driving..Yikes! Sometimes there are 2 square cardboard pieces included in the seal kit, never found what they were supposed to be used for.

They are IN the package, why would they go through the hassle of packing these if they were waste? Some of the early stuff are perfect rectangle seals, no round bulge.
