It would be easier to convert it to flanged axle shaft. With the stock tapered shaft the wheel studs are in the drum. The axle shaft has a key way and the drum is an interference fit with the tapered axle shaft the key just keeps if from slipping and a nut with a cotter keeps everything together. Flanged axle would be stronger to. I don't think its worth messing with the old tapered shafts.
