More progress today. I am really happy to be at this point, it was the biggest step other than tuning and boost tubes. All the other stuff is nitpicky and small.
Here is my solution for the difficult mounting position:
I think it looks great, but just to fill that opening, you need to cut a lot of metal. I think I'll get 'er reinforced later.
Next up: fixing the couple coolant leaks, save up for exhaust manifold while cleaning up wiring, refitting the interior, reattatching exterior parts like the airdam, etc., etc. It goes on and on. Cant wait to be done!
