Lunchbox, A team van roof spoiler?

[graemevw 823]

My nephew has painted his lunchbox as the A team van. Done a good job of it too, he's only 10!

He has asked if i can make a roof spoiler for it. Any ideas on how/what to make it from?

I could make him a nice full size one from steel, but not sure about a 1/12 plastic one.

Or, anything from another model i could modify? Would be easier!

Honda city turbo ( Willys Wheeler) roof spoiler and some mounts ? or form up some alu bar , ( B&Q )

Its this kind of shape, HCT looks more of a lip type spoiler?

I could probably just bend a flat bit of alloy but need to incorporate some kind of easy, strong, child proof fixing (screw up from inside probably)

Countersink some 'cheesehead' bolts straight through the top of spoiler & mounts to inside the body , washers and nuts , sorted :)
