I researched* this quite a bit on f150forum looking for verification that all 9.75 rear ends are 3.73/1 and all 3.73/1 are 9.75 and I could not find a counter example for the gas engines. Each time I build a truck with a 3.0 on Ford.com I cannot chose 3.73 ratio; if the data for the gassers hold, then all diesel engines have an 8.8 inch rear end.
*by research I mean I solicited input from the forum crowd. I read the sales guides too, but couldn't find a black and white answer, thus all that I have is anecdotal.
