1970 Dodge SuperBee 383 Rear end

[Richard Boyd]

How do I verify that my car has the correct numbers matching rear end?

If you have a 489 case, that’s a good start. Other than that, I’m not sure.

No "VIN Numbers" on a rear end, so you need to start with the build sheet - it will list the part number for the rear along with the gear ratio. Actually, it will show the last 3 digits such as 489 or 742. Then you can check the date code on the rear. I know Dana's where date stamped on the rear end housing tube, not sure about 8.75 rears, but I suspect that might have been.

I’ve never seen a date stamp on an 8 3/4. Build sheet or fender tag should show what rear end it came with.
