I havent really been able to dig up solid info on what my truck is running for a front and rear diff. I am trying to hit one of our suppliers up for some free diff covers but dont know what to start asking for. Some reason I got Dana30 in my head but I am probably not correct, if one of you folks could help me out it would be awesome.

 

Rear is the corporate 8.25. Front is the corporate 7.25.
