I remember as of the 1990s it only had around 50,000 original miles. Around that time, both my grandparents had passed, and my uncle took possession. That's when its history becomes a little uncertain.

As it sits now, it has 131,663 miles on the clock. It's extremely likely the sprocket is as bad as yours! Wow! Thanks a ton! Looks like there's more impetus to perform exploratory surgery.

LOL yeah I don't really know how the truck was running. The timing chain was so stretched it almost touched in the center.
