Peter,
I would recommend you give David Thomas in Codicote a try as he services my Fulvia and all my previous Lancias in the past 7 -8 years, it's run by David and Karen his wife, and it's a friendly family operation with David hands on in the workshop, David used to race Alfas, a task now taken on by their son.
Other LMC members I've recommended him to also seem to have been satisfied with his service, he's an acknowleged Alfa and Fiat Coupe expert and I'm sure he'll be able to help, Phil Ward of AutoItalia Magazine takes his cars there, and a number of years ago AutoItalia featured David & his Garage.
