ALL GM 10 bolt rear differentials indeed have a cover plate with > 10 bolts holding it on! The check / fill plug is located on the left (passenger) side - front - center of differential. Requires 3/8 square drive tool to remove the plug and re-install.
Recommend having qualified personnel check diff lube.
