Rear seat could be removed, spare wheel was mandatory and it had to have the same diameter as the other wheels - but the width was free; so the Ford Capri had a bicycle wheel as a spare...

Thank you Frank for that good information. Well done Ford with the Capri 'spare' wheel!
Regarding transmission- what about for instance changing bellhousing material to magnesium rather that iron- I think that was allowed?
The Escort RS1600 homologation papers show as a 'variant' lightweight fibreglass bonnet & boot (page 20) and also aluminium skinned doors (page 22) but was not homologated until Sept 1970 I think. Would they have been allowed to use the panels?
