I don't think there anyplace you can actually purchase the manifold conversion. I'm getting the impression that everyone who has done it, makes their own.
And yes, there is considerable difference between the 1000 and 1100 exhaust systems. The exhaust is ported specifically to a model of engine, using an off-year exhaust will cause performance to suffer as it will change the back pressure in your system.
