Thanks for the informative link.

I also agree with Noglider in finding a shop with a large assortment. Learned the hard way when I ordered two different pairs for an Italian crankset. My hope was that at least one of the two pair would work. Not so and didn't want to fuss with trial and error grinding. Was lucky to find a shop with a very large and variety of pins. My guess there were at least six different type of tapers.

IMHO, makes a difference in getting a pin precision close and use a good grease. The arms set nicely and its easier to take apart for future service.
