I have read quite a bit about these cowls now, but I just want to see if I can confirm what I think to be true. You can get the 67' cowl from Dynacorn and it will fit in to my 66' Coupe?
I would suggest using the '65 - '66 inner cowl patch panels for a '66 coupe.
I don't see how a '67 cowl would work on a '66 without a great deal of fabrication. The vent patterns are different, and I think on the top the center will be too tall for the '66.
NPD shows the top panel, but I don't think it is available yet, but should be available soon.
how hard is it to do a patch repair kit till the whole thing can be done at a later date? i have seen these repair inserts with sealant and am wondering if anyone has tried them. i just need something to last me till i am able to do a proper full repair.

Kristen,
I put the "top hat" cowl patches on my '66 coupe about 7 or 8 years ago and they still do not leak.
I cleaned up the stacks on the cowl and use some fiberglass to patch a couple of areas, then used some silicone to seal the plastic hats.
Before you do any repair work, I would also recommend cleaning out the cowl area thoroughly after removing the heater box and drivers side vent fresh air assembly. You can reach around inside the cowl and get most of the stuff out.
Once you get all the leaves and dirt out of the cowl, use one of the cowl covers - either a clear plastic or magnetic mounted one to keep additional debris out of the area.

i bought the plastic "top hats", but then i found out my rust was much worse than i expected. so i bought the lower panel patch from cjponyparts.com, i would have bought the entire lower panel if i had to do it again. this is a pain in the ass, if you can get away with using the plastic things and some rustoleum do it.
i called npd in jan. and they said they would not have the upper panel till mid 2008, so i had to repair my old one which was pretty bad too.

i know that the cover might be a last ditch effort and that the damage could be really bad, but i guess that i am just hoping for the best but also researching for the worst. i have found a few sites that have some info on this, but this was one of the best and included some great pics (I tend to be a very visual type person)
If you pull the fenders off check the cowl drains and make sure there isn't seam sealer blocking them and creating a dam to keep the water in. Ford didn't build these cars with high quality in mind, otherwise they would have painted or treated the cowl area than leaving it bare metal and would have paid more attention to not seam sealing over the drains on some cars! A utility (sheetrock) knife works well for cutting out the seam sealer if it is blocking the drains.

As said, the cowl repair kit only addresses the raised area at the fresh air intake points. If you have rust out anywhere else, the "top hat" repair kit is not going to be of much help.
A proper repair is to remove the cowl cover which includes the drilling out of many many spot welds. This is a very involved project and the windshield needs removal also.
I think that if you decide to do the repair, wait until the new repro cover is available. That way you can cut most of the old cover out without worry of damaging it. This is one of the biggest pains in the ass projects on the vintage cars.
On my 67, as a way to keep trash and water out, I fabbed two pieces of sheet aluminum to fit the openings. On the back side of these pieces, I applied some thin generic weather strip to the perimeters. I applied some of that magnetic tape inside of the perimeter. The magnets keep the covers in place and they seem to work. You can paint the covers to match the exterior, if desired. I used poster paper to create templates for the covers.
I remove the covers before driving, but there has been times that I have forgotten to remove them and they stayed in place even at highway speeds. Even if the cowl was OK, this is a good way to keep leaves and other trash from entering while the car is parked. My yard is full of leaf shedding trees.
Mustangs Unlimited has a full 65-66cowl replacement, like the 67s. After reading an article about cowl replacement, you might need a professional to help you out with it.
That or you can just replace the metal around the vents. Either way, the windshield and upper cowl are coming out. And you gotta be careful abot not letting your 'stang sag when you remove the cowl.
