I went and looked at a D2AE four bolt block today. I saw something I dont remember and it has me wondering what the deal is with it. On both decks there is a hole with a pin of some sort in it. It moves but is not loose in the hole. In the picture the hole in question is just above the headbolt hole. Any idea what this is for? Just want to make sure it is kosher before spending my money on it. Thanks for your help.
