Can anyone give me some advice as to how to make a mould from this spoiler plug I'm making?

I'm thinking a split along the top and barriers to the front and rear edges?

This is exactly what I was meaning, unless you need the strength of the 3 sides id be trying to find a way to see if I can release like this.

However looking at your drawing the 'point' were the release is is much more curved than I though and will create a mechanical lock if its accurate. 
 
 
That's why i'm now leaning towards doing it in two separate pieces and bonding them together. it's going to be stronger and give a bigger mounting surface. also easier to lay up and release the parts.

I haven't done anything quite like this before so any advice on lay up, trimming, bonding, etc would be much appreciated.
