Here's a photo of my 1969 '489 case showing the RATIO tag. They used a orange paint splotch just below the fill plug on the other side to indicate a Sure Grip. No tag for that, at least in '69 that I'm aware of.

All I know is 68s had a round disk. Pretty sure it continued through 70

Some info from "Moparts" below. I know I've seen the "orange" splotch talked about on other sites too. So maybe it all depended on which plant the car was built at whether it was an orange splotch or a tag?? Mine was "orange", I've owned the car for 44 years and I'm the only one to have ever done anything to the rear end. That's not to say other '489's were not identified differently, ie., a tag like you say. That's the beauty of Mopar, nothing is an absolute with these cars!


From Moparts:
After 1965, a tag was affixed under one of the

carrier mounting nuts to identify the ratio. If Sure Grip equipped,

an additional Sure Grip lube tag was sometimes affixed; later years

sometimes had the filler plug painted orange.

Based on the car in his avatar and the OP not specifying a later model it would have both tags.

In relation to later years the change came into effect in 69. The orange paint was applied to the filler plug. Forward from that were various paint stripes of different colors depending on gear ratio. For example a 3.23 got two black paint stripes. There are also several other markings on the pumpkin, housing tubes etc...

I have had a lot of 69's and have not had one with the limited slip tag.....However, some could have snuck through the various plants on early 69 builds.....

You've got valid points about his avatar car and his lack of information on what car he's working on. BUT, he did say a '489 case and I don't think those came out until late '68 (for '69 MY cars) IIRC?

So, the '489 must not be original to the '64 Polara in his avatar.

As far as all the "paint stripes" and "colors" you mentioned, I agree with all that. I also have two '69's with a '489 case and neither have a Sure Grip tag, just orange paint.

Mike,

Correct....

We are just going off limited info.

489 case was late 68 IIRC for the early 69 builds and forward....

Actually my 65 300 had the tag. It was a late model year build so I would say the started putting the ratio tag on in 65. I don't have a suregrip so there's no disk.
