    Evening all, while replacing my rear leaf springs it dawned on me I never checked the rear diff.. drum brakes with a 5x4 pattern but we’re scratching our heads on identifying this! Any and all help would be appreciated.

      If you look on your ring gear I believe you should have a stamped gear ratio on it.
