There is some confusion here. First the answer: it's 380934-S2, 8-18X1/2PAN 5/16,XREC,DRILL TIP, 2 required. This part number is not in the 2014 AMK bulk section, but may be in the "packaged hardware" section for 68 interior console (page 249) under stock number, F-1099 (28 pieces - $14).
Agreed, confusion...I'd say MUCH confusion...
Several online vendors sell and photograph the AMK products and have them listed by AMK number, enabling us to see what is in the bulk items NOT pictured in the AMK catalog. That being said to help you get a look at what is in the pack of 28 pieces for the AMK F-1099 68 console package. NOTICE: No matter what online vendor you choose, not one of those 28 items pictured look to have a "DRILL TIP".
Furthermore, as not to muddy the waters anymore than I just did, (but here I go...stirring again
) I agree that the original screws were self-drilling because the bracket the consoles were mounted to the dash with were NOT pre-drilled, thus requiring a drill-tip screw. (If you compare multiple original examples of this bracket side-by-side, the hole is NEVER in the same spot)
Though I have worked more on 67's than 68's, I recall always finding drill-tip screws in this location, but more of the variety of the wide head, self-drilling version that hold the Roof Drip Side Finish Molding in place (stainless molding that holds the window, upper weatherstrip in place). This could be a plant-specific/time period detail. I will not add hardware numbers to reduce my "muddying" and will quit stirring for the time being.
SUMMARY: I think you had better locate another unrestored original example before simply buying what AMK provides.
...and by looking at the witness marks on your console (your picture), it looks as though what I recall typically seeing there was used also on your console
