On top of driver's side fender liner or wheel tub.

Did u look under your seat up under the metal between the foam. I think they put build sheets there also.

My 76 is missing the SPID too. I think the glovebox was replaced sometime in the last 38 years.
There was a build sheet in the seat springs but it was from the 1980 truck the seat came out of... If you're lucky your seat is original.
