By 9.25 are you talking about a dana 60?

If so, do a search or two and you will find more Dana 60 and 44 info than you can read.

I think "pinion depth" and/or "case dementions" would be a good terms to use in your search. Also stry the big diff supply houses, thier sites are full of info.

Good luck with your project, I just did a dana 60 for my jeep and it was a big job (my first time inside a diff)
