What posi differential assembly will fit in my 85 4x4 pickup? I want to go posi front and rear instead of lockers or the stock open.

 

Torsion made one for the supra that requires a different bearing set to install in truck. Don't ask me years.

 

i would take a real locker in the rear any day of the week over a ls. i have a truck with a ls in the rear also another with a lockright, i drive the truck with the lockright when i dont want to get stuck. but for limited slip options there are like a detroit
