A week goes by and no exhaust manifolds. So I called the auto wrecker and, after two hours, they realized that the shop they sent them out to to get scoped, failed, and were not sent back to the auto wrecker. Since that was the only set they had, I called auto wrecker #2 and they had a matched set off of a 360 coupe with 13,338 miles. They were more expensive but come with a 90 day warranty. I received these exhaust manifolds today and will inspect them with my mechanic.
FNA had all the parts for my transmission (first and second synchros, all the associated parts that go with them, all the gaskets and O rings for the transmission case, etc.). They supposedly arrived at Ferrari of San Francisco today and will presumably be at the shop by tomorrow.
