im slowly putting myself back together here and decided to delete the ac because the unit went, from what i can tell i remove the stock bracket that held the ac all together and im left with empty holes. i imagine i can just leave them empty right? the ac delete pulley uses 3 of the original bolts which i already have in place on the front bracket thats attached to the water pump. aside from that there are 2 holes in the front of the driver side head that have me wondering what they go to. i attached some pics and circled those in red. i dont recall removing anything from them but this project has been spread out over 6 months and i might just be forgetting. can anyone tell me their purpose (the 2 holes circled in red on the head), and if i can leave the stock ac mount bracket holes empty as it shows in the picture?
