Dave, it seems that every time you post I end up in the garage looking at something to do with my Roadster.
The near side has a gap of about 1" between bonnet and bumper. The off side the bonnet just touches the bumper.
Close examination using a straight edge shws that the near side bonnet half has slightly more curve on the bottom edge than the off side.
So, does it matter? I doubt it.
But I'll have to adjust the near side bumper, because now I know it annoys me....!
