Bolts missing from the PET, can anyone find em?

Hi folks,

I took off my camshaft cover the other day and unfortunately the bolt that goes through the camshaft sprocket driver is stripped. What's more, I can see in the PET that the piece has a hole in it (where my stripped bolt sits), but it never shows a part number or size for it. I've pointed to the hole in blue:



Next, there are two bolts that hold brackets onto the cylinder head. These were super rusty, and I want to replace them altogether. They're visible in the photo, close to the front spark plug.



Anyone know the sizes of these things? I figure I should just order stainless steel replacements from McMaster Carr so I know they won't rust or strip in the future.

Cheers!

The pan head (allen) bolt that holds the rotor to the shaft is M4 by 6 mm. Secure with Loctite 221.

The cylinder head bolts are m8 coarse. They extend into the head about 3/4 inch, so add that length to the shoulder on the head for total thread length.

Fyi, never use stainless bolts in aluminum, they will gall and you will be left with a mess to sort out. Regular factory bolt specs are fine.
