F1 GTR (97 Longtail) - road conversion?

[BelfastBoy]

I've actually read the answer to this question somewhere before but can't find it again - can anyone explain why it's impractical / not possible to convert a 97 longtail F1 GTR to road legal specification? (If the answer is somewhere on this forum, apologies and please point me in the right direction.)

Thanks - I think it was the gearbox that was the real impediment to a road conversion. To comment on one of the other points - there's a good few road-legal supercars lacking rear windows (Mercedes CLK-GTR, Porsche GT1, some of the wilder Pagani Zonda derivatives with roof scoops).
