If there is a V at the pinion yoke and the driveshaft then yes that is the angle, if it is an inverted V(I can't make that sign on this keyboard ) then make it a so the driveshaft is the left side of the V and the pinion yoke is the the right sid of the V, both pointing at the bottom of the V I really hope this makes sense BTW, if the car vibrates under WOT or on deacceleration try 5 degrees difference next time Some cars will vibrate at 7 and some don't I think it depends on the U joint size used.
