the 2.0 16v and the 2.0 8v will share the same gearbox and the blocks are the same anyway so would be the same shafts for both conversions
so you could get the conversion shafts and and hubs, then theres the idea of corsa gsi shafts with mk2 cavy inners and standard outers, of you could try chrisastley and see if they do a conversion shafts cause im using courtney motorsport shafts there massive and use 2.0 16v inners and corsa gsi abs outers
