They sorta did...around 1975 or so they started making the cowls from galvanized steel. When I sent my '77 to the junkyard, that was just about the only non-rusted part of the car... Yeah, shoulda cut out the cowl and saved it...DOH!
that's gotta be weather stripping. i had the same problem got it all replaced for about 60 dollars and it's perfect now.
mine does this also. some guy told me the only way to get to the place to fix it is to cut open the cowl, and weld a piece of metal over where it leaks. hmmm maybe one day it will get fixed..
You don't have to cut open the cowl and there is at least one article on the subject in the "Tech Articles" forum.
ah, i figured. i stated that, meaning that the guy didnt know what he was talking about and took an 'easy' way out..just thought i'd clarify that from before. later
maverickchick, turn the water hose on, low flow, and poor directly into the cowl vent...1st on the pass side. While doing this you need to have the pass door open so you can watch the inside of the car around the bottom of the dash. If the cowl is rusted out you should quickly start seeing water leaking down on the floor and possibly into the package tray. Then move the water more to the drivers side and do the same. Hopefully you don't see any water inside yet. After this test, move the hose to the bottom of the windshield. Odds are the windshield gasket has cracks in it, especially around the corners. Again, watch inside the car for water coming in. If you do see water at that point you need to plan on ordering a new w/s gasket and have it installed by your local glass shop. Let us know and we can direct you to a parts source. It's best if you have an extra hand doing this, them with the hose and you looking up under the dash...or vice-versa. Good luck with it.
