Does anybody know if this support rod is on the 68-70 B body for any specific reason? 4 speed, automatic, etc? It seems to be a pretty rare support rod. Out of all the pictures/articles on support rods I have only seen this rod a couple of times and never found a real reason for it. Thanks

I had that one in a 70 column automatic car ..kinda a pain as it mounts with the dash frame
My opinion from an engineering standpoint: Triangulation
The steering column is a relatively long class-3 lever in this application. If a driver weighs 250lb and "hangs" on the steering wheel, that translates into ~500-750lbs of vertical down-force at that spot on the cowl. Adding the brace (a compression gusset, if you will) distributes that force diagonally -mostly outward/somewhat downward- to the side body. Whether it's "necessary" can be debated, but manufacturers typically don't add-in 'stuff' without a reason. Just my 2¢
