    The real difference with the ’58-up is the drive shaft runs in the bushing above the pinion. Pre-’58 models, the pinion had an extended neck that runs in the bushing. That means the older ones had a much larger bearing surface. But the ’58 is fine as long as not abused.

    Ah yes…The larger diameter of the pinion surely helps with durability, didn’t consider that…
