Looking at a 71' Demon

Take a look at AMD 1/4 skins from www.521restorations.com (they have a pricing on the website and give a discount to moparts and fabo memebers)

I just bought a set for one of my Demon's and they weren't too bad. I've bought all of my AMD sheetmetal through them. And Yes it fits very nice.

Full 1/4's are only needed if you are replacing all the way up to the roof line. Otherwise the 1/4 skins will work for what you described.
