Does anybody know a good site with pics on how to fix cowl vent leaks.I saw one somewhere a while back and now I can't remember where.I'm talking about removing the fenders and cutting the ends of the cowl and repairing it through the ends.I'm not exactly sure where to cut.

I can't help with any info that does sound like quite a project.

Although just a band-aid, have you seen those cowl seal plates? It's a sheet of plexiglass with two spring-loaded locks that slip in between the vent rails, once rotated perpendicular to the rails and released the spring load retains the plate which is lined with some kind of foam rubber gasket. If nothing else, it could seal out moisture through the winter months if you still need to drive your car. Just a temporary fix, but still a slick little deal

Is this the site?

Here's a good one, too:

...and some reading:

Good luck, this is a tough repair on the early Mustangs.

Thanks Steve that first one is one that I was looking for.I don't want to completly remove the cowl,I'm hoping to be able to fix it through the ends.I haven't actually tested it yet to see how bad it is.I removed the fenders and the little rubber plugs so I could see inside.Lots of crap around the vent and metal looks a little rusty.Tommorow I'll get out the hose and see how bad it is.I'll probably be bugging you guys every night as I frantically try to get the car ready for the body shop.I've never owned a 65-66 mustang and there a little different from my 68 so I appreciate all the help I can get.Once I'm done maybe I'll be able to help out somebody else with my new knowledge of the early mustangs

Good luck with the cowl. Cowl repairs are a pain. Get a cowl cover for your Stang or Stangs as soon as possible. All '64 1/2s to '68s are known to have cowl problems. There are a few ways to repair them. The hardest and most expensive is to remove the cowl cover. That is 178 spot welds that need to be cut just to remove the cover. There are patch panels available to replace the corners around the vent top hats. You can also buy plastic topless top hats that go up the fresh air vent tubes with lots of sealant to stop the leak/s. Some folks remove the fenders and cut a hole in the side to access the cowl. These are just a few examples of cowl repairs. One other repair that some folks have done and I do NOT recommend is sealing the cowl vent with bondo.
