I want to put in a posi diff in my truck as it only has the crap open diff in it at the moment- they call it 2wd but its really 1wd. I have found a reman mopar cone type on ebay.

I have looked on google and some say they are ok but what I have read over all is that they are junk.
Would I be better off to buy the clutch type diff.

 

Would need to know what spline count axles it wants. Aside from that, should bolt right in.
