Dana diff widths.

hi all, i have a Dana 60 with #603222-1 stamped on the right axle tube. my research tells me it's from a 70-72 B body. will this fit in a 70 E body? if not does anyone know the difference in width dimensions of these two? i went to the diff/axle thread but that info seems to be gone. thanks to anyone who can help me..............djs
