Kept getting water down dash under drivers seat.

mine does that too...how did you patch the rust, fiberglass? also how did you pull the glass out?
i will eventually have to do mine before my whole windshield frame falls out lol

my windshield was cracked, so i got them to pull it and give me a day to fix.
Unless you have the tools don't do it yourself, I got it to bare metal and fiberglassed the 8 holes. primed and painted it was well worth it no more leaks.
