Not saying MOB isn't correct, and that maybe the most economical way to go but it seems that it would take a while to search through McMaster's stuff. If time is no object then keep searching. However to some time is money or another way to look at it, our finite lifetime slipping away. My advice is to just order them by part number from someone reputable like (IMO) Ron Ayers (link below). There are others that are equally reputable some have higher prices and free shipping, some have lower prices and horrendous shipping charges. If you're not mechanically inclined then chances are you are not going to need many parts so there is no need to get familiar with McMaster-Carr's huge catalog. If at some point you become more mechanical then their catalog is definitely your friend and a very valuable resource.
First thing is that the numbers that you've posted are not part numbers, but rather diagram reference numbers. The part numbers will usually have a hyphen in them.
It appears to me that you need one: Diagram Reference 92153D;
Part Number 92153-0489; Description BOLT,SOCKET,6MM; cost $1.69
You may need (in my garage they disappear at an alarming rate, once you drop one it vanishes) the plastic washer that goes under that screw
part number: 92200-0157 $.95
For the metal cover screws: Diagram reference 92153H;
Part Number 92153-1810; Description BOLT,SOCKET,8X15; Cost $1.74

Now if someone (MOB?) wants to look up exactly what you need from McMaster-Carr then just ignore all that I've said.
Best wishes to you.
