drivers side exhaust manifold 66 dart
If it's the stock 273 style that kind of wraps around the steering column, I think you'll have to put the manifold in the car, lower in the motor, & then attach the manifold. I don't think it'll go in attached to the motor unless you pull the steering column. Somebody else here has probably done this a lot more recently than I have. Hopefully they'll give you a confirmation of what I've said. Either that, or somebody here will tear me a new one!
Well, what do you know. Somebody answered you before I could even finish typing! I blame it on arthritis in my wrists.
