My thanks also for the picture, mumbles. The wider bushing in 1959 helped with the pin-to-rod wear problem. However, the real problem was the pin beating loose in the piston bosses. The larger pin diameter helped prevent that by spreading the load over a larger area. And the roller bearing all but eliminated the tendency to rotate the pin back and forth.
