Wanted: 8 3/4 Pinion support shaft from a cone type sure grip

Well I guess you didn't understand what I was trying to tell you. You will not find a OEM shaft and pin. They don't make the parts any longer. That is the part that always failed in them. When the cones quit holding the two spider gears spin more than they are designed to. Usually wind up welding one or both spiders to the shaft which in turn rips the pin out of the case. Most of the time you can't get both the gears off the shaft and sometimes the case is so worn out the hole winds up torn up.
