In the searches on this forum there is either an arrow or a silver ball that you line up with the pointer.My ring gear has both so which one do I use? This is a canadian built truck if it makes any difference.

The ball, which will be a few degrees advanced from TDC is what you use to set ignition timing. | | | | | Joined: Jun 2008 Posts: 145 Wrench Fetcher | | Wrench Fetcher Joined: Jun 2008 Posts: 145 | Ah, so the arrow on the ring gear is the U/C mark,that is why there is both.It seems the 2 get interchanged in old forum posts. Thanks
