Power steering gear box question

In doing a refresh on my smallblock '68 cuda, I am changing the heads and the headers. Problem is one of the header tubes (cyl. #1) is hitting on the p/s box, right at the sector adjusting screw. Never had a header hit there before. Looks like I would have to collapse the tube about 1/3 to 1/2 to clear.
Now my question is .... is there a replacement p/s box that is smaller over all? Didn't know if there was something new out that I wasn't up on. I haven't paid much attention since getting my car done. Is there a Mopar box that could work?
Thanks
