Help! Doug's headers in 67 barracuda

Thanks 72bluNblu, good to know about the column being longer on the 67's. Can I just take the column out and cut a few inches off that tube. It looks like there is just a bearing sitting in the bottom correct? I guess I just loosen the collar nut (that sits on the shaft just under the column) and then with a bit of luck I would be able to pull the bearing out...?

And yes, I guess I'll have to dent the pipes for the borgeson pump and the torsion bars.
Is there a best way to do this? I was thinking maybe put some tape around the area to reduce scratching and maybe put a large round socket against the pipe and hit the socket with a hammer?

Or should I use high localized heat and then bang it directly with a hammer?
I should have just bought the steel header and then get it coated after it was test fitted LOL
