Its taken a while mate, I'd suggest when you or anyone else tackles this conversion you get the engine fully built and all the extra goodies ready first.
Looking forward to driving it with Clio gearbox, if I like it with that then I think new gearbox internals cryogenicaly frozen and a diff will be the way forward.
The freezing process is ment to strengthen the metal, sorry chocolate, by around 600%
Cheers Foxy, I hope to make it to one of the Yorkshire meets soon
