To break it for the gearbox seems to be a bit shortsighted to me... What else is wrong with it and should it be saved?! If it would only take minimal work to fix it then braking it for parts ain't too far short of Mongol rally territory

... I mean no offence but there are few enough of them left (especially special editions; you wouldnt see anyone breaking a Sisley for the doors let alone upholstery).
I'm sure you can get a 5 spd gearbox without breaking that one...
This is a plea for clemency!!!
Kev, give him the gearbox from the fizz and save the Tacchini!! You know it makes sense!!
