There is a posi unit that is currently in a '67 chevelle 12 bolt rear that I have purchased.� Can anyone identify what the unit is called or what it might have come from???� We counted the teeth and did the math.... its a GM 4:33 posi, but thats about all we know. I did find out also that the numbers 9 39 on the ring gear verify it's a 4:33.
I have two pictures on my website at:
