I am putting the neon green cabbie

...sorry...back together and have struck a snag I have not come across before.
The doorcard on the driver's door refuses to fit properly.My usual response of swearing at it has failed me...
The 'poppers' all fit correctly,but the top will not stay clipped in to the top of the door,with the top fitted into it's clips the poppers are about a quarter inch too low.
After swearing I have tried a heat gun to bend the card at the top without success,I found traces of silicone when I stripped the door,so this is not a problem that I have built in,somehow!
With the poppers in place,the door handle release lines up properly so it's the top bit that is out of shape,any suggestions as to how I can 're-shape' it,please?
