How to get rid of push button shift cables

Boy, those shift cables on my Valiant with a push button Torqueflite 727 sure do get in the way of everything. I'd like to install headers, but I think it's impossible with the shift cables in the way.

Would you guys please edumacate me on how to convert an early PB 727 to a floor shift? I apologize for being clueless.

I think finding a correct floor shifter and modifying the old cables, or having new cables made, would be too difficult and expensive, so I am thinking manual valve body.

So how do you install a manual valve body on an old PB 727? I assume that maybe it requires a special valve body? Can you point me to anybody that I should contact for parts?

The 727 that I've got is well-built, it was somewhat expensive and it works well, so I really don't want to get a different transmission. Thanks a lot, guys.

The pro stockers back in the day relocated the push button console to the floor a lot of times. You might look at something like that.
