Help with exhaust manifolds for a 66 cuda

I've searched looking for info on the exhaust manifolds for a 66 Barracuda and coming up short.
A friend of mine gave me a set of exhaust manifolds from a 92 dakota which was told to him would fit on the early a-bodies. I have two questions.
Does the engine need to be lifted to get the drivers side factory exhaust manifold off? I have tried every angle and removed the starter and exhaust to try and get this manifold off but I have not had any luck.

What Modifications need to be done to have these dakota manifolds fit.
My car has power steering. I was told they will not fit with power steering. Only with manuel steering.

Can anyone give me guidence on what direction I need to take?

thanks,
David

I would recommend staying with the factory exhaust manifolds especially if the motor is a 273/318. I've never installed these on a car with power steering but can assure you, you will need to modify(cut) the steering column a bit. Do not cut anything until you know if it will work. I have yet to see anyone using these with power.
To remove the old manifold, remove the driver side mount and raise the engine with a jack under the pan about an inch. Keep arms & fingers up top. Don't trust the jack.
Heres a pic of clearance issues.
