It is interesting that the 76 service manual has a typo as it specifies the J57 as an SJ Grand Prix hardtop coupe, and the K57 as a Grand prix hardtop coupe, while your VIN built sheet specifies the opposite: K57 = Grand Prix SJ, J57 = Grand prix.
Seeing the VIN Build sheet explains everything. Thanks again.
