I'm not sure that would be necessary. Yours looks a little less curled than mine, but it has a distinct curl (or looks like it from here, anyway), as does the illustration in the 1948 catalog. Why is it curled? I would argue to accept the round shape of the swing arm shank. I don't believe mine has been molested. You can actually see the finish on my clip. And yours clearly hasn't been molested. Stretching the swing arm over the clip provides the tension.
This is just one of those minor seemingly insignificant details and dilemmas that will drive me crazy.
The bottom line, guys, is there's no way my clip has been bent, and there is no way for me to bend it to make my swing arm rest on top of it.
You would think that they made one box, including the speeder mounting pieces, to one set of specifications, and that the Circle-H, BE and Circle-U speeders would all fit. Only because it seems crazy to make a different box - or at least the same box with a different middle clip, for two different suppliers.
Let's move on for now. But put me down as 'still flustered and undecided'.
