we just bought a 2nd addition for our stable. a 65 with a fresh 289, car runs and drives great! has some rust issues.....no biggie. but the defroster sucks! I looked at it tonight and all the hoses are hooked up, door moves good but when you open the defrot ducts it still leaves the rh floor duct open and about 50% of the air comes out there. I dont see where there is anything missing or broken. It just looks like a piss poor design to me. I have also worked on alot of these cars for other problems and have noted the same thing with them. Are they all like that??
