The problem is, the wires need to enter and the design of the stock bracket has an edge that will at bare minimum make the wires difficult to handle, at worst the won't even fit.
Sure, measure twice, cut once, but I didn't expect such a snug fit. I cannot lower, I cannot rotate as the clearance above and below is of a so few millimetres it is a perfect fit.
Get it done!!... Fast forward: By tomorrow I'll be able to say, I wrapped all the lovely newly painted areas to protect from grinding sparks, ground away, and put a coat of primer over the bare metal, after of course more wrapping to prevent over spray..
