That's right, real Escos panels do not fit. It's sad but true
I once wanted to do this but saw the light
The Escos is such a nice looking car that a rep seems like a good idea, but to be honest you come to realise that you'll just get shown up when a Scooby etc wants to race and people will always always pick fault with it.
But if it's what you want and you can spend decent money on it, then go for it.
