1963 and 64 steering column question

Well, you could pull the wires out of the plastic connectors, then pull the wiring harness out through the top. On each column. Then switch harnesses.

I've done this without disassembling the column. But you could also do that, and while you're at it, switch the shafts from one column to the other.

Me - I would prefer not to cut/splice wires.
