Quote: I've never seen a 489 case with a sure-grip tag. As far as I know, the one pictured is for a Dana 60.
Thanks for the heads up on this piece of information. I will definitely look into this area of detail. I have is a posi rear in this car. Do you (or any one else involved with this thread) know why they would put the metal tag on the Dana style rear end with posi but not the 8 & 3/4 with posi? I thought the tag was used to let the person filling the rear (with oil) know that the posi oil additive was required.
