One arrow points to a two digit code that looks like 53. Please confirm that number. One arrow points to a blank box. This indicates the car came without Sure Grip (SG).

One arrow points to a three digit axle assembly code. This tells us the rear end gearing, SG or not, the axle body application and brake size. 189= B body 8.75, 3.23 gears. open (non SG) and 10" brakes.
