Ok so what do I use the gallon of MTL(70W80 GL4) in that I bought last
summer as per recommendations of this list... Can I use it in the
rearend???..Good thing I didn't have time to use it in the 76 with
overdrive.... Darn and I really looking forward to having the transmission
shift as smoothly as everyone said it would..Bob
