Pickups are always a bit difficult because of the back angle and short side. Often a top looks better when the back angle of the window opening matches the very back slant. A bit of a dog leg as an alternative might add some interest and make that side panel look less bulky (but of course, all of this is personal taste). I said modified because of the limitations of the way the bows are shaped on Dan's top mechanism. Here are a couple Lee style tops (not too sure the second one is his or a copy, the stitching doesn't look as interesting). He was big in Pasadena in the '40s and '50s. Baskerville's car had a Lee top also if you can dig up any pics of that.
