Removing Steering Shaft 1966 Barracuda

Hi. Just put the engine back in the other day....but....forgot :BangHead:, that the left-side exhaust manifold doesn't fit in between block and steering box and shaft....

Any idea, how to manage putting on the manifold without manipulating the engine again?

I am thinking about removing the steering shaft out of the coupler and the bracket that goes through the firewall... ?

Doing that, I hope to get enough space to put the manifold in place.

Thanks, Robert
