Help with blocks ASAP!!

So my rear end is on the floor of my garage and I'm trying to put in my 4" maxtrac blocks....I know a lot of you are going to scold me for running 4" blocks but lets leave that for a rainy day!! So the blocks are angled and they have two holes on the top. Which holes do I use? There is a centered hole and a hole towards the rear of the truck on the top of the block. I don't know which hole to use......help ASAP!! Thanks guys

 

Which hole keeps the centering pin in line with the hole in the top of the axle? I have no personal experience, but that's the hole I'd use.

 

LOL at this ^^^
