Question one is, should I replace my open rear with a posi unit or a locker, and why if you don't mind. This is a daily driver.
Second question is my truck rearend a 28 or 30 spline?
Thanks!

 

I put an Eaton posi in mine. I drive it over 1000 miles a week. You dont want a locker on the street. Its to unpredictable and can get you in trouble.

Your truck has 30 spline axles.
