Now that I have decided that a lockright locker is not what I need for the truck on the street and started looking for clutch pack style I have seen two different models both reported to be dodge originals. One seems to have the clutches with a large spring and the other the clutches with 4 small springs like a chevy 12 bolt. What is the difference in the two and which is better.Also will a unit that has the abs ring fitted install in a 89 ram housing that does not have abs. thanks once again for the help
