Driveshaft compatibility...pretty urgent

[aidan]

Considering buying a 91 mk2 GTD here in the UK, but a driveshaft has 'fallen off' according to the seller, what other mk2 driveshafts would be a direct replacement?
I do not know at the moment the engine or gearbox code

thanks, Aidan

any mk2 shaft will fit. check the inner cv flange size.90 mm or 100mm
