Here:
Trigo Wheels | Wheels For Your Cobra! and when you click on the Alignment Tool it says it's only for 5 pins.
You know, I vaguely remember Doug telling me that 5 pins where a PITA when I was visiting ERA's shop. But I had already spec'd out 6 pin hubs, so I wasn't really paying attention to anything regarding the 5 pin jobs. In fact, I could just be imagining that conversation and it never really happened.
