Ok right now i am in the process of trying to figure out which posi unit i should get for mustang. I have a 8" rear and have noticed it is not a lot for me to choose from. Right now i am trying to figure out the difference between the "ford traction lock trac loc posi unit" and the Powertrax no-slip. Can anyone tell me the difference between the 2 and also the difference in the installation like what is needed and so on?
Ford traction lock
Powertrax
Powertrax
