fc repair panels

[shifty biscuits]

ey up. has anyone come across any repair panels for fc\'s?
i need to do a few repairs on my shell so just looking for a shortcut really. sills and chassis rails would be good if i could find them.
if there are none available im gonna look into forming some up at work so be good to know whats out there, might even be worth doing a small run if anyone else needs them to help keep a few on the road.
