Not really a step by step but you get the picture.
You can see when I have them side by side. The oem makes a funnel(cone) towards the crank bolt vs the ati has a cylinder straight opening. I had to nearly make it flush before I could just get a socket in there without extensions. But its installed on a g37. Not sure your clearance on the 370. Socket thickness is fine just haveing space between bolt and radiator shroud to get it in there
