I just got my hours cut last week. Working only 32 hours so I don't want to put any money into re-arch springs. I never thought about the Pinion angle. I guess since the back of the spring goes up higher the pinion angle would change. I would have to move both front and back to keep the same angle. I going to have to re-think this one out. I get one of my sons to trig this out.
