Chris - Welcome back.
Sorry I'm in a bit of a rush, so these were the first two photos I could find.
Even though the Cordite/Spitfire combo is different to the Spyder/Herald one, I had the same issue.
So I cut a 'wavy' line along the bottom of the bonnet.
Which allow a full 90 degree opening without fouling the chassis.
Hope that helps and I can get better photos if you need them.
Good luck, Paul.
