How did you get the steering box out? I am trying to replace the power steering box in my 67 Cuda but am not sure how to disconnect it from the steering column and then around the headers. I have the 3 bolts out that hold it in place.
I cheated...mine came oit AFTER i removed thr engine.
Without removal that task is tough and my box is a manual. The power box is larger i am told. I suspect you may need to unbolt a motor mount or two. Be careful not to crack thr distributor as you push th engine aroud to make room.
Hopefully someone will chime in with a tip for removal
The shaft on mine has a splined coupler. There is a pin that drives in to hold them together. If you drive that pin out you can lever the shaft off the spline. You may need to loosen the steeing column. And using a pry bar to get the coupler moving may be necessary. If you want it i can take pics of it disassembledto help you visualize it. There are some videos on YT. If i saved one i will send you a link.
