I have a set of these sitting on my workbench and I think you'll find there are two - the middle length pins - that are the right size. That leaves you needing another set to get two more pins though.

I got the replacement rear hybrid yesterday from flm and its correctly machined in the pinion brg area. Got it assembled last night and its like the front - zero play and butter smooth.

I was dismayed to find these bulks will not work with UE knucklehead towers though! Never have seen this mentioned anywhere.
