Yup, that’s what it looks like. And since it’s a narrowed B body 8 3/4 axle they’re probably the 10x2.5”, large bolt pattern (5x4.5”) version. Which are super common, most parts places will carry the drums and usually even a few different brake compounds for the shoes. For most kinds of street driving a good set of semi-metallic compound shoes will far outperform any of the OE offerings.
