I have a 65 malibu convertible with a munchie 4 speed and a 283. It has the original rear in it, I believe. I am looking to change to a posi rear. I use the car as a sunday cruiser and do not plan to change much else. what gearing would you suggest and what is the best way to go about this project? Thankyou for any advice you can give.

Actually, one of the easiest ways is to install a PowerTrax unit in your current differential.

Love my powertrax !!!! get the Performance Locker Version only!....with that 4 speed
