Dear Paul,
Welcome to the forum! This site is great for sharing expertise (or otherwise) and sourcing hard to come by parts. Why not post a few pics of your 1600 Coupe and let us know the colour, age and details etc. We can then advise you accordingly.
If you are looking for anything in particular, post a message on the "parts wanted section."
Owning a Lancia these days requires some determination and the ability to become "your own expert" as the official dealer network ceased in the UK in 1994!
However, when their on song they are great fun.
Best,
Chas and Anne.
