Did 1969 camaros with 327s have a posi rear end?

I have a 1969 camaro and I can't tell if it has a posi rear or not. I don't want to to a burnout to find out and the muffler is in the way so I can't check by the number of bolts. And is this a rare car? I know this was the base V8 for a couple of months. It was a powerglide transmission and the shifter on the column instead of the horse-shoe shifter on the floor.
