I am pretty sure water leak inside the cabin is a very common problem with all early mustang, but I just want to know those who experienced it, what did they do to try to fix it. My stang really hates rain and she collects everything on the floor pan anytime there is any rain. I hate to do this but will have to go through another floor pan replacement. Any trick to seal those worm holes off?
Had anyone thought about the idea of completely removing the cowl, coz that's one place rain love to sip through?
