I am trying to find what rear end came in this Buick Electra. I have the vin number if it is needed. I have googled for this information but it is all too vague. One site says it is a 2.78 rear end and another site says its a 3.07:1 rear end. I would really appreciate some information in regards to this. The rear end that is currently in this vehicle is a 3.73 and not the original as far as I can fathom. Thank you in advance
