hi, i'm woring on my 1951 3100 panel and i'm replacing the pinion seal and i'm trying to figure out what rear end is in it. its a 10 bolt oval shape with a drain plug in the cover. there is a stamped number, NK1011 on the passenger sida and a cast 273 on the drivers side.
also, i need a pinion shaft bolt. any suggestions where i may find one?
thanks
