Best bet would be to call a Ferrari dealer to confirm. I have never heard this so I'm sorry I cannot answer. If you find the answer to be true please re-post so we can help others in the future. Best of luck, I'm sure someone else will see this and reply.LoCanGlass said:I have a customer looking for the back window for the 400i and someone said the 365 GTC (which I have in stock) is the same one. Can anyone either confirm or deny this?...I don't want to ship it all the way up north and have it not fit. Thank you.
