GM #273449 was never a SERVICE-available part so it won't be found in any of the standard parts catalogs, either the "free-standing" variety or the earlier which were incorporated into the regular P&A Catalogs.

Thanks, Joe. Any idea of what the specs

were for these screws?

I'd say it's a virtual certainty that the screws were phillips PAN HEAD, had a "notched" (self-tapping) tip, and were cadmium finished.

As far as OD and length, I'm not sure. However, I feel pretty confident that they were either #10-16 and about 1" long OR #12-14 and about 3/4" long.
