CPP PN# 6372LDL dropped cross member

Does anyone know the centerline of the 3" holes for the dropped cross member for a 1970 C10? I need to know the dimension from the lower frame bolt to the center of the exhaust hole. Also I would like to know what the dimension is from the bottom of the dropped cross member to the bottom and top of the exhaust hole. I ordered this piece a week ago but they did not ship because they were out of black. My truck is at muffler shop now and they can bend the pipe...I can weld on the mufflers at home. I need to get the truck home to start tuning...help me....please

Thanks...Bill
