[Vwdiesel] Main bearing shells - 5th grooved goes where?

[Shawn Wright]

Ok, I know this was covered before, but searches didn't find it - I have a 
new set of main bearings, 5 grooved, 3 solid + the shouldered set for #3. 
So in which cap does the 5th grooved one go? Presumably the one with 
least load, but which is this - #1?
