Wow! I have a 69 350ho with the T/A gauges, quick ratio power steering with the cooling loop, 4 speed m20, 3.55:1 safe t track rear, and it's a convertible that is PHS documented, Matador Red/Black Deluxe Int, White Top... Mine isn't in this shape, though! I hope he gets what he's asking.
Can you post the PHS docs for this (your) car?
