Just got my swing arm back from Aluminess. They repaired the cracks and repainted the arm.
Huge thanks to @cthayn for driving the swing arm out to CA and bringing it back. What are the chances of finding someone so close to home who happens to be going to the exact place my swing arm needed to go? Very much appreciated.
Also impressed with Alumniness. No questions asked. They just fixed it. Very rare in todays customer service world. They did add a few drain holes in the swing arm. Look to be about .25".
Overall, very happy with the power of this forum to connect people and Aluminess for standing by their product.
And, if you live somewhere where freezing and rain occur, might want to bust out the drill . . . . .
