Trying to figure what steering boxes I have.

I have a '68 with power steering. I've been trying to make up my mind whether to have a 12.7:1 fast ratio conversion by Powersteering.com done to my original power steering box.....or to go with the Cardone IROC box (pn 276550), also with a 12.7:1 ratio.

Ideally, would have prefer to keep my original box with new innards but that is a whole lot more expensive than doing the Cardone conversion when buying the Cardone box at a local parts store ( no shipping something very heavy each way).

Not having made up my mind, I bought a Cardone box from Advance Auto Parts just to compare to my original box. I was curious as to the ratio of my original box and wanted to be sure the Cardone box was actually the 12.7:1 ratio.

Doing some checking using a homemade degree wheel and a protractor, these are the results I got. They may not be dead nuts but they are close.
----------------------------------------------------------------------

My original box: Number of turns lock to lock: 3

One full turn of input shaft = 20.5 degrees of output shaft turn

Input to output shaft ratio: 17.5:1

Total degrees of pitman arm travel lock to lock: 62 degrees
-------------------------------------------------------------------------------------------------

Cardone box: Number of turns lock to lock: 2 3/4

One full turn of input shaft = 23.5 degrees of output shaft turn

Input to output shaft ratio: 15.1:1

Total degrees of pitman arm travel lock to lock: 65 degrees
--------------------------------------------------------------------------------------------

I see a lot of conflicting information about what an original '68 power steering box's ratio and number of turns lock to lock should be so I don't what I have here. I'm sure it is the original box.......Any ideas if this is a standard power box or possibly a fast ratio?........For what it is worth, I have the long pitman arm (5.8 inches center to center)

I was surprised by the Cardone box being so far off. Has anyone else bought one of these and found out they were not the 12.7:1 ratio? Maybe I didn't get the right one.

Thanks.....Dave
