I can't confirm for sure but I would think you would want the alternator, bracket and idler arm, WP pulley, Crank Pulley, and power-steering pump and bracket.
It should bolt up. You could also buy underdrives, alt. and bracket, ps-pump and bracket.
You might be able to switch pulleys on the alt. that U have. Also you could up-grade to a 130a alt. off 95-up stang.
I'm pretty sure U will need ps. pump though.
I did this conversion on my 76 motor but I have manual steering, so ps pump wasn't a concern.
Hopefully someone has done this and can confirm but I just thought I would respond with what I know.
