Re: 59ab & 8ba
Brian's comment caused me look at my 59ab crank.
The answer then became obvious. There is a single hole at the center of the bearing.
I suppose the crank could be drilled for the inserts, but not practical.
Now I must decide whether to just get new 59ab rods or get an 8ba crank.
I hope this discussion will answer some questions for someone else later.
