Centro C4.1 Chassis

[MarkGoulding]

I have picked up a well used Centro off ebay, It has a steel chassis on it and a second used one was thrown in the box with it, I have put one up against the other and they are the same size and all the holes are in the same place, but the one on the car has 2 bends on it (one where the servo would go and a bigger one where the front arms connect) and the other one is flat until it bends at the front arms.

Are both these chassis correct but different versions, or has somebody just stuffed it in to a wall and flogged it on,

Thanks for any help
