posi question

Did the 10 bolt 2.73 rear come standard as a posi trac unit?

With the drive shaft disconnected on my 10 bolt, I can turn the drive and both axels spin.
Is that normal?

This is on a '89 305 TPI.

Re: posi question

Limited Slip rears were a option (RPO G80) available with any gear ratio. Nothing was standard if GM could make it a extra cost option.
