A10sausage,

Take a look at the following topic from when I was having the same confusion:

You might find the whole topic interesting, but for the most part, I think your question is answered by Dave's post at the link ("sausage", "link" -- hmmm ;) *smile*) and then, maybe, my reply two posts below his.

The one with the smaller hole is part 65-306 for a longstroke A7 & later A7's & 10's 1948-1953 , the other is I suspect 65-317 A series 54-63.

The small holes are correct. The big hole ones are actually drain ones from a B31/33.

I second what Brian said, I'm not sure what the big holed bolt is for....
