While sitting here having lunch, I 'chatted' with Doug from there regarding this.

In a nutshell, he said its too old and no longer supported.

He showed me a newer model but the parts were totally different.

I think the part is mislabeled in the manual? What 68 is pointing to sure looks like a spindle, which 69 pointing to a pulley claims to be?

I tried to save the chat we had, as he suggested one place that might be able to help, but it hasn't shown up in my email (yet).
