Help with headlight assembly hardware part #s
 

Newb just diving into some small projects on my SC - can anyone tell me the part numbers for #20 & #17 in the diagram? Or are they standard sized hardware, in which case what size are they? Finally, in the interest of self sufficiency where can I go to look these up? I scanned the PET for my 911SC but came up empty handed. I found the image below in the forums but no part number key with it.

Thanks in advance for the help!

Illus 905 in the 77 PET.
17 is a cheese head screw 999-014-008-02, and
20 is a half-round screw 900-016-014-02
