No need, I've installed 3 sets of the HRpartsnstuff braces. They fit perfectly and come with good instructions. They are quality pieces that look good as well.They look like they should fit around the UMI braces but have a feeling I’m going to have to contact them for a definite answer.
And I would've bought Mac's from SSM if I had known he had them (forum sponsor and generally good guy 😉 )
I have them installed with the UMI supports.
