Fitting curved box lid stays

Hello, I am in the process of making a large box. The lid is 400W x 250D x 30 H and weighs 1.5kg.

I will be using two butt hinges, and a curved 65mm long stay at one end.

I have never fitted these curved stays before. Are there any installation tricks I should be aware of to making it fit and not hit any sides etc?

Thanks in advance for your help
