Got my bulkheads and some what got a little plumbing done in the overflow box. For the rest of the night I'm leak testing the bulkheads in the overflow before I get the plumbing finished.
Here's a look into the overflow.
No1 is 2" drain
No2 is 1" to a sea swirl
No3 is 1" emergency drain
No4 is 1" going to 4 return lines built into the tank 2 on the overflow and 2 at the peninsula end.
