2-series aluminium bumpers - upside down?

I have a good straight aluminium 2-series front bumper, which I am considering fitting to my '80 model as the existing one is slightly damaged at one end.

The problem is that the good bumper has a pair of holes in the top where someone presumably mounted a pair of extra lights. I don't want the holes in the top, and am wondering if there is actually a top and bottom on the aluminium bumpers, or can I flip it up the other way? It'll be getting painted black before it goes on, so existing scratches, etc. won't matter...

Obviously, whichever way up I fit it, I'll have to drill the set of holes for the '80 front spoiler...

If you're painting the bumper, why not fill the holes first?

By the time I add aluminium MIG or TIG welding cost to the exercise, plus the extra work of grinding the welds back, I may as well go to the wreckers and look for another bumper. For the sake of two small holes, it just doesn't seem worth it.

I have some stainless-covered GM bumper bar bolts, and I'm thinking that if the bumper won't invert, I can fall back on putting them in, but I'd rather have a nice clean top surface on the bumper.
