Good day all. I'm just getting back on my truck after a long pause. It's a 51 1/2 ton. I need to know what the 2 bolt holes are in the firewall toward the top just to the right (looking from the front)of the 2 holes that attach the vent opener bracket. Also, it's between the vent bracket and the speedo grommet hole. I'm welding up none used holes, and just can't figure out what these are for, and if I'll be reusing them. This is my 4th AD truck, but my first one in 10 years or so. Thanks in advance.
