Installing 4 spd pedals

Hello, I apologize if I missed it but I searched before I posted. I was wondering if anyone new of a good resource on "how to" install 4 spd pedals properly into a 72 Duster?

Car was a column shift auto, I have removed the dash assembly to redo it and I want to install these pedals. I am going to also replace the steering column with manual steering column for a floor shift car and remove the power steering and replace e with manual box

Thank you.
