WTF is an AAR Center section? This 3rd member is a 742 case 1968 was the last year for that, AAR E bodies did not come on the scene till 1970. At that time it was 741 489 and Dana's offered. This Center has aftermarket auburn cone type sure grip with Red springs, the oem ones did not have colored springs, ring/pinion is also aftermarket.
