Athough DynaCorn makes a good product, I have never had good luck with thier product, things just don't fit well. I may be an exception and others may have had good luck, so I don't want to cast them in a bad light. Just my experience. If you need both doors I would search for good original doors or make sure the "Repop" doors are made on "Original Ford Tooling". I'm sorry I can't recommend anyone. Before you buy from a wrecking yard, visually inspect the doors just for peace of mind. My experience with anyone here on this site has been great and if they say it is good condition, you can bet they are. Ron Moore with R&R Classics, see link on left side of your screen, may have good contacts such as A&M Mustangs, they are a local Mustang wrecking yard in Sacramento, Ca. Good Luck and Do It Right the first time. Hope this helps. Mike
ps. Where are you located? I do know someone who has several 68' coupes for parts cars. What color is your car, I can check on a price and availability for you.
