If your not going to race this car, it will handle and drive better with the standard rear end. The standard rear end is always in prefect revolutions. The outer wheel spins more then the inner wheel during a turn. The Safety-Track has clutches that have to be over come buy the engines power. Next time you get a chance and have both go into a lot and make some figure eights with each kind. You will notice right away how much smoother the standard rear end turns. By the way both back wheels propel the car with a standard differential, it's just when one wheel spins the power will flow to the spinning wheel.
When driving in the snow I hated posi rear ends. You would go up a hill and both back wheels would spin and the whole car would go sideways, were as the standard rear end would have on wheel spin and the other keeping the car straight..

Back in the glory days of the early sixty's all those Pontiacs used standard rear ends.. Smokey said one of those clutch rear ends wouldn't last 100 miles..
