Steering column identification & grounding issue

[ByALongShot]

So I picked up my '64 just over a year ago and it had a lot of things already done to it by the PO. Unfortunately there are a few parts that he wasn't sure of the origin since he got them along with it when he bought it himself.

I've been having trouble figuring out what this steering column may have originally come from. It's an automatic, without tilt, has a hazard button, and it's already got a Grant wheel installed. Anyone have any ideas from the photos?

Also, I'm have trouble with grounding for the horn. I originally thought it was a problem at the rag joint, but it turns out I lose continuity a little further up the line. Any thoughts of how I could overcome that without a long ugly grounding strap?
