I found a 1985 Jeep Xj with the HP Dana 30. I could not get to the Tag to see what gear it is, and am suppose to call the Yard Tomorrow o see if it is in fact a 4.10. My Question What is the Chances of it being a 4.10? I though all 4 Cyl jeeps had 4.10's But now am reading mixed things. it had a manual trans if that helps.
