Limited slip or not?
Just bought a restored '64 with a .030 over 455/tri-power. I was told that it has a non-posi rear, so I wanted to verify. I raised the rear tires and spun one of them to see what the other one did, and it did not turn at all. Same result when I spun the other tire. It took more effort than I thought to spin each wheel, & the drive shaft turned both times. My knowledge is that with an open rear, other tire should spin opposite, and with a posi rear it should spin the same direction. What may be going on here?
Thanks for any guidance.
