420 Sport exterior parts / louvred rear tailgate on a First Edition?

[MagicFlute]

Hi, has anyone established yet whether the exterior changes from the new 420 Sport can be retrofitted to an earlier First Edition?

I'm particularly interested in the louvred rear tailgate/window. I really like the look of it and wondered whether it could potentially be fitted to an existing Emira, assuming the underlying tailgate/body mounting points haven't changed.

I'd also be interested to know about the other exterior parts - front splitter, side sills, rear spoiler/diffuser etc.

I've seen a few comments suggesting that the parts should physically fit but may be extremely expensive to buy individually from Lotus. I've also seen suggestions that some 420-specific parts might be restricted by VIN, although I haven't found anything definitive confirming that.

Has anyone spoken to a Lotus dealer/parts department about this yet, or managed to get part numbers/pricing?

I'm not looking to turn a First Edition into a fake 420 Sport - I just really like some of the exterior changes, particularly that louvred rear end.

Sorry if this has already been asked. Thanks in advance!
