I just got my package from Combo Motorsports. And when I was on the phone with them I had requested NSA rockers. But on their invoice it shows that they are SA, however they sent me guideplates for them. The box that the rockers come in dont say either way. Is there any way I can tell just by looking at them?

 

If they are Pro Mags and are SA, they will have the little guides shown in the circle here .

 

Thanks a lot Shoebox! (Great cam removal/install guides btw) Looks like I got my NSA rockers after all.
