Well here in Nashville we have had lotz of rain, and today I was able to catch my 93 Marq, and its water leak covering the rear pass floor board, leaking in the EARLY stages. Today I looked at it and the water is JUST starting to puddle in two streams so to speak, meeting at the same place where the front pass. seat belt strap bolts down in the rear floor board area. SOOOO it appears the water is atleast running in at that point where the belt bolts to the floor...... Now I will have to look a bit closer at it since it appears to be the entry point pehaps.
