Confused!

[Ben]

Hi all,
Noobie here and with a bit of a dillemma (spelling?) on the build.

It's a VW beetle floorpan that me and my mate Kieron restored to as standard spec, ready for a different bodyshell.

The bodyshell is going to be a steel box frame supported fibreglass number in the style of a 90's LeMans GT Racer.

Right now the quandry is this, will i need to SVA this?

The details;

OG floorpan with V5 (tax exempt)
OG engine & Gearbox
OG front beam suspension
OG Rear Suspension
OG brakes

in fact the only none original parts will be the frame sat on top of the floorpan and the shell on top of that.

I thought this is just a simple case of body swap no SVA, but Kieron anonymously spoke to the DVLA and they said it would need SVA.

What say you?

All advice knowledge and input greatly appreciated.

Cheers
Ben.
