Thanks Dan!
I see that I was confused by what I thought I was looking at.
Now, I may be in need of more information. Under Group 4.661 in my 1929-1950 MPC and in a '29-'54 MPC I found online, I don't see any listing for the Group 4.661 bolt that covers the 1946 1/2 Ton pickup.
I wonder if one could put together other brake system parts that would allow for the connection of the brake line and the brake light switch.
