I would like an end view of the aluminum crank with good lighting to see what the spline teeth look like to see it they are grooved deep enough to work over a long period of time the plastic ones have very little teeth and over time the plastic will dry rot.

Thanks for writing in. I'm having a picture of the spline of the 39-121 made up for you right now, and I'll have it uploaded as soon as possible. That said this handle is made of diecast-zinc, so I am confident it should be sturdier than a plastic replacement. We'll get back to you with pictures. Many thanks.
