Ahhh, my eyes! The default style in SketchUp is a travisty, Window->Styles->Edit and uncheck Profiles, Extension, and Endpoints. Then I'll be a much happier critic

Ok just been up and held my 140.3 up against my brothers A05, and yes by inverting the back panle it ought to fit, just, it'll extend beond the case proper and into the void of the front fasia, and you'll have some problems with the retaining clips for the front fasia (the width of the rad being the problem) but hopefully with a bit of judical fileing you can squeze the rad in there.
