Getting ready to install the painted dash and gauges. The dash screws and bolts onto the cab. The cab section has a support or cross member that runs from the A pillars on each side. In that support there are five, about 1/2" diameter holes. Two of the holes are somewhat "D" shaped. These are at the center of the support and one on each side of the windshiled crank assembly . The other three: one on each end near the "A" pillars and one about the center between the windshield crank hole and the left "A" pillar.
What is/was the purpose of these holes? I don't believe there is a missing part(s). I received this project disassembled, but the dash was apparently one of a few parts unmolested since assembly. Just want to make sure on this re-assembly so I can avoid re-working the whole dash later. I don't think they are drains, since as I learned from others recently those are in bottom corners of the windshield channel.
