Whats up everyone. I'm new to this so sorry if i sound like an idiot. I just have a few ?'s about my 1977 f250 3/4 ton. I was wondering if anyone could tell me what a Dana 44-9f means and if it's original to the truck. The bill of material #610010-4R, cant find the date. Pretty sure the ratio is 4.09. Can anyone confirm this? Second i'm positive the rear is a Dana 60 but don't know the ratio on that. Thanks for the help.

 

I am looking for the same thing myself. I was wondering. On the web of the differential there is a 03. I thought it was supposed to be a 44 on it. Can anyone help. This is the numbers reading from the diff out. 5 31 744 610010 4r. Any help would be nice. Looking for a rebuild kit for the outer's on both sides.
