Doug Jennings (or maybe from his machinist, now that Doug is
retiring)...

I bought mine years back, to replace the stock pins, along with some
Delrin bushings. Since I'm slow to actually get things done, I never
actually got around to doing anything with the pins until the urethane
bushings were available from Rick at SS, so that's what I actually ended
up using. I think that Delrin bushings on the street, with the
cantilevered pin design, is a bad idea.

Doug's pins are very well machined and feature proper inside radius at
the transition from the larger diameter part to the portion where the
bushings go on. I haven't seen anyone else's pins so I can't comment on
those. If the pins have more than the most minute machining marks where
the diameter transitions are, then there is a risk that the machining
marks themselves will act as stress risers... It might be worthwhile to
polish that area of the pins (preferably in an axial direction) to
remove the marks.

For those that have bent or broken pins, where did they break? At the
points where the pins bolt onto the crossmember, or at the roots of the
diameter transitions where the bushings are?
