Sam, I wonder if it was just a timing thing with supply and demand. A 4.10 posi rear is a 4.10 posi rear to the guy on the assembly line. I'm sure the paperwork would have shown a "BV" rear but maybe the guy couldn't locate one quickly so he grabbed a "BE" rear. I'm just guessing, but who knows. It could have been a warranty replacement as well. So where do you plan to store all these 69 Z28's?
