Thanks for posting the link Trevor.
The key bit for me is this:
"To keep the original registration number your vehicle must have eight or more points. This must include the original or new and unmodified chassis, monocoque bodyshell or frame."
To me it looks like a matter of interpretation regarding mods to the chassis prior to the inspection: The way it reads to me is that a new chassis needs to be an unmodified one, barring a switch to a tube or spaceframe chassis, for example, whereas the original chassis is just that, whether it's been drilled, welded, lightented, etc or not.
Any DVLA inspectors out there with a view on this one?
