Driver side floor wet - where's the thread?

[wedgemon]

I recall, but, can't find, a recent thread on driverside leaks that soak the floor. My truck (80 k10) drips on my leaft, and sometimes my right foot in the rain. And, the floor is soaked after any rain when she just sits. No obvious running on the bulkheads.

Anyone know where to find the thread or to find this leak? And what to do about it?

Thanks!
