Re: FAST RATIO PITMAN ARM
Not sure, never had one of each side by side to compare difference. My car has the manual steering box but I haven't pulled the pitman arm yet.
I have an idea that the output shaft on a PS box is a larger diameter than on the manual version (in the same was as the drag link is a larger diameter with PS), but hopefully someone else can confirm and answer your Q.
