Yeah, the 58-63 10hp gearcase is pretty unigue. The tough part to find these days is the driveshaft, the extra power was tough on the smaller gearcase when water got inside. Most 10hp driveshafts are worn in the lower bushing area, the lower bushings in the gearcase are usually whooped out as well. Complete 10hp gearcases will swap out from 58-63 but be careful trying to mix/match parts between different gearcases, the driveshaffts and gears changes around 1960.
