Sorry, I guess Image Station does not allow a direct link to uploads. Too bad we can't upload attachments. That feature has been "temporarily" disabled for a looooooong time. Ayrton is correct, the tubes were made by a company in Costa Mesa, as I recall, and the yoke, etc. was assembled by Inland Empire Driveline.

When I snapped mine Inland Empire said it was obviously not their fault. They sent the tubes to Costa Mesa, but they would not stand behind them, said is was obviously a result of abuse. (Sound like a Ford warrantee claim?)
But Inland Empire was good enough to build me a new driveshaft out of aluminum, and not charge me a nickle for it, and it looks more robust to me than the Ford shafts. I think I better get a stronger one built for the new motor; I don't want to have to walk home from any events.

 

The company that the HD guys have been thinking about is PST, and several Mustang guys rant and rave about them, so hopefully they build a better shaft.
