G80 question

[Ttypenut]

I bought an 86 GN today,looked at the production sticker on the decklid and it does not have the G80 Does this mean no posi rear or just not limited slip?

 

[buickpower]

they are the same. you have an open diff

 

[Ttypenut]

is that good or bad?
posi or not?
should i shop around for a better rear end all together?

Get a posi unless U want to burn the pass. side tire for a mile or so!!!!

Call Summit or Jegs to get a posi carrier for your car.. I bought mine from Summit and I think it was $440.00. And the carrier I bought was the Eaton Posi unit... HTH.....
