On a 12 bolt chevy, where is the pinion depth measurement taken from, the machined surface for the caps? I want to replace my gears, but do not want to buy a depth measuring kit. I was wondering if I had a machined flat bar that would bridge the caps mounting points, could I use veneer calipers to measure the depth from there, minus the thickness of the bar? Thanks, Sean
