I picked up a D44 front from a '73 suburban last week, and I was cleaning it up over the weekend, and spied the model # markings: 44-8F does anyone know what this signifies? I know that the 44-50F is a thick-wall axle tube marking, but I have not heard of the 44-8F??

Thanks! <IMG SRC="smilies/usa.gif" border="0">
