Thanks, maybe the numbers will be searchable.
Doesn't the template for mounting the clock housing only require 4 small holes, not one big one? Maybe someone was trying to mount a dash clock flush without the housing?
Or, they needed to fix the windshield wiper motor and got frustrated with working from the bottom.
You are correct - one hole in the dash in the dash photo in original post.
And, as shown in a thread linked-to in a post above:
clock installation drilling template - 4 holes need to be drilled? (the largest is 1" diameter)
Clock Installation Instructions for Instrument Panel [truck] Clock Housing (54/55st) By the way, that dash looks to have been cut-up/out in other areas - such as the holes to the right of the ignition switch?
