So I decided to remove the ball flange and install 3" V band clamps. Also ordered a cross over pipe and cross member from B&B very nice pieces.
Here is a shot of the pass side showing header clearance

Very excited my third member showed up so now I can order my drive shaft and start exhaust. I went with 3.90 and the Wavetrac posi unit. Talking to a few guys running autocross the 3.73 was a bit tall in 2nd gear so hopefully this will be overall a good ratio.
