I didn't get much further than this,
I got it welded and test fit the quarter, I have a high spot so it needs adjustment
Here is the only other pic I have of this at the moment, But basically it was a piece of 18ga that I had made into 5/8"x5/8" angle then I trimmed off one leg just past the bend, It would have been much easier to just replace the one 5/8" leg and not cut down the side but there was some rot that creeped down and I wanted to make sure I got it all.
The yard was a disaster so the rest of my weekend was spent being a landscaper..
