I have a 8 3/4 with the 489 case with these #'s on it 2881489 1 , A ,R ,9 ,AARPW , the pinion yoke has the # 264300 (I've been told it's the big one) ,it's got the cone posi unit . it's about 55 1/2 inches from the end of the axle housing flange to the other , axle flange to the other is about 60 1/8 inches , drum to drum is about 60 5/16 inches , drum brakes are 11 x 2 1/2 . When I bought this rearend years ago , I was told it was from a B-body . Can anyone tell me exactly what it's from ?
