1967 Mustang Coupe Build (Electra)

so you replaced the lower cowl (patches) thru that hole in the side?
If you gut the dash (instrument panel, glove box, heater, etc. you might weld it from under the dash.

I had a cowl leak on my 67. Those rings are rusty were they are welded on. I used these little plastic things on mine and some windshield sealer. Did it all from under the dash.
