[hoodygoodwood 70 3 Cars]

My wifes P reg 306 Cabrio has been written off in a minor accident and I have retained possession of it from the insurance company , I will be stripping it for parts some of which I will be keeping and the rest will be sold .

Its a 2.0 litre 8V  (the one with the airfilter in the cam cover ) and has a BE3 gearbox which I may keep as a long term potential replacement or source of spares for my 309 GTI's , I was wondering if the ratios would be suitable and if there would be any fitment issues .
