I have reference books that list the HCC-AX is the 16:1 ratio, manual box used in the GT and the special handling option. Some vendor catalogs list the AW as the GT box and the AX as the power box. I swapped in a 16:1 HCC-AW box in place of my original HCC-AT (19:1 manual) to get the quicker ratio. I have a pet theory that whichever box is the power will have less wear than either manual since it was under less strain over the years having the power assist absorb the work. Any thoughts on which is the real GT box and opinions on my pet theory?

I've always heard that it is the 16:1(fast ratio) manual box. In fact, it is the box that came on my 66 GT. I have since switched to an HCC-AW box ( which is also 16:1) and the power steering set up from the 66 coupe I sacrificed to save my fastback.

in my experience, if you ordered a car with special handling and no p/s you got the HCC-AX and all power steering cars got an HCC-AW. Of course, I have seen exceptions though. Either one would be considered correct in my opinion.
