Yes I have and it would seem they are going to try and sort it out.
"G'day Jared, thanks so much for letting me know, and I'm really sorry that you have a part that doesn't fit. I've made many of these that have fitted fine so I suspect the part you have may have moved on the cutting bed or something odd. That's not good enough and I'm kind of embaressed that you received it. I will check the other flanges I have here against a head next Tuesday (I should be able to get a head by then) and send you another flange.Once again, I'm sorry to hold you up and thanks for letting me know."
I will see what happens but it would seem he is eager to fix the issue
