I just did this mod yesterday. I stripped the 14mm x1.5 ->-6an adapter(aluminum) I will try again on tuesday when I get parts from summit. I would also recommend:

instead of

it is a 45 degree since the straight one hit the perrin rotated mount uppipe. That is how i stripped my fitting.
Now my driveway looks like a murder scene.
