There is a grommet that goes there, FORD PN 373195-S. I don't know if it is still available.
Best bet is to go back to NAPA and under the complete overhaul set it should give the contents of the kit. FORD calls it Grommet (distributor mounting).
If you try FORD, ask the counter person to trace the number. If punched in as is, it most likely won't show. There are most likely more character(s) after the S. Have him give you a delete date if the number is no longer good.
If no luck...try FEL-PRO and then if no luck notify me.
