Replacement electric drum brakes needs to be selected based on the axle weight rating to ensure they have the necessary stopping power. We do offer electric drum brakes in your specified size, 12-1/4 x 3-3/8-inches, and this size comes in ratings for 8K, 9K and 10K axles. All are displayed on the linked page. Your axles should have a sticker or plate that indicates their weight rating.

You'll also want to note the brake mounting bolt pattern to make sure you choose new brakes that match. The brakes shown come with 4-bolt or 7-bolt mounts, such as # AKEBRK-8 and # AKEBRK-10.

As long as you select brakes of the correct weight capacity and mounting pattern you do not need to worry about the shape of the magnets.
