bonnet adjustment

[JonyTVR]

Hi guys

noticed on my chim after going to Leven open day today my bonnet sits too low at the top making it it so you have to almost 'slam' it shut rather than rest it and push down, it also doesnt line up quite right with the wings, however I cant see how to adjust this? I assumed that you would be able to just move the bonnet catch up but I loosened off the 2 bolts and it wouldn't budge and I'm abit stumped now how else you would change it?

cheers

Jon
