Milodon road race pan

I was just about to order the Milodon road race pan. But it says it only fits the 73-76 k frame. Is the 67-72 k frame that different?

I imagine it would need minor mods to fit ?
Isn't the main difference between them the sway bar mounts ?

Plus does anyone know if the mopar 380hp create engine come with a windage tray ?

If not I imagine I need a stud kit to fit one
Would there be machining involved ?
