73-2 would be floor mats. 73-1 was the Air Cleaner, Dual Stage H.D. The -# was just to show which of the two possibilities it was.
So, if you saw a 3 in column 73 it would be both the floor mats and the air cleaner. Since yours is blank, your car had neither option.
Codes for Columns 74 and 75 are not shown anywhere in my PHS documentation.
My documentation is for 1968.
