Thanks guy's.
Bigbadswingdaddy we know what want to end up with its just how to get there we not sure of,as for the gearbox my partner has a very bad knee due to a skiing accident so a manual is a no go especially a crash box. We want to keep it as standard looking as possible and not do anything irreversible so it could be returned to standard.(we are keeping all removed parts as we feel we are only temporary custodians of a beautiful vehicle)
I do understand that i'm going to have a lot parts shipped over and hence asking who you nice people used so far i have found these suppliers
