Hey Ross,
No such thing as intrusion, this place is full of help and wisdom. Go to the site:
www.classicperform.com and go to the TECH area, scroll down to steering and there you will see diffrent ways of installing the ps box and columns. Im gonna keep my original column and install a Toyota ps gearbox that fits in the same place as the original box that came on my 1948.
I have to fab a bracket from the frame to the column which I found on e-bay(#300162732931)for land cruisers, but I have to extend the top of the bracket so I can move the box over beef it up and make little more room for my 327 and block hugger headers. After that you have to find a pitman arm that will work but I have ways of doing that also, later.
Hope this helps some. Good luck
Mike
