47-55.1 Turn Signal Switch/Column ID

[SRA1]

I'm trying to identify the column in my 48. It's an old tilt wheel, and I've watched several videos on changing the turn signal switch, but none of them look like my steering column once I take the steering wheel off. I"m hoping maybe someone can aim me to a site to identify the column based on the turn signal switch (which is the problem). I sent a request to Delco, but no response after several days. Picture of switch connector attached. The switch has a 47203 in the plastic. The column has another 6 wire plug from the switch handle with wipers, and washers, but I don't have any of that, so it's not required. I found a switch that looks close, but has one extra wire on it, and a set of clips on top to which the extra wire runs. Any suggestions greatly appreciated.
