I measured and marked where the centre support would interfere and removed some of the cooling fins. You can just see the marking out for the right side that has to be cut.
You are not imagining things, the ac core is bent after we hit a 6' roo a while ago.
Then mounted the end brackets to the light and hung the light from the grille shell, had to notch a small section of 3/8" x 1/2" for the bracket to fit.
You can just see the top of the mounting bolts in this pic, right on the line where the chrome finishes.
