ok..if you got the gears in the hemi did you get the pinnion gear as well..??..if you didnt take it back coz its supposed to be a matched set..
if you did get the pinnion as well now you need the housing because 2.60 and 2.78 ratios stand alone for housings..3.08 3.36 3.55 4.1 4.44 will all use the same housing..
back to the original question,if you do have the crown wheel and pinnion gears from a 1 tonner it will not matter coz you wont have a yoke to change and the axle splines are the same..
