I ordered a medium summer shield from clearview and it came today. It's quite a bit larger than the original but sadly I can't get it to fit the bottom brackets. It comes down quite a bit further below the headlight and it seems to ground on the forks. I'm wondering whether it's a good fit on a standard bonneville but won't work on the america because of the thicker forks or the rake angle.

1) does anybody have one of these fitted on an america?
2) can anybody verify that our fork shrouds (above the brace) are much thicker than a standard bonneville's? How much?
