Joji,
It definitely needs pulling up as when bolted loose touches in the middle with gaps either side. But this car has been through quite a few knocks, nothing major, but enough that could upset the fitting, although the fit is quite symmetrical. I will talk to Richard about it when I next speak to him. I will take a watching brief on the issue rather than race into it, as plan to check fit the door catches ....then start on the chassis next.
