Have you looked at the .gov website about radically altered vehicles?

Cheers
I understand that. It's not radically altered just a standard Land Rover front. On a standard Land Rover Chasis albeit a shorter one with standard Land Rover suspension and axels.
If the vehicle has less than eight points, a second-hand or altered chassis, frame or monocoque bodyshell is used, the vehicle must have IVA, so that it can be registered. A 'Q' registration number will then be issued,
I cant find the gov document that this is from, but the statement crops up on forums all over, so it must have come from somwhere -
Basically, you can do all sorts of stuff, but the chassis is some sort of untouchable. And that's exactly what you are proposing to change.
