Those seats are beautiful !!!! There is no way in heck, that I wouldn't use those in my Demon. And if those are 1970 bucket seats, that is a one year only seat. Same seat they put in the 1970 Hemi cars, and 340 Dart & Duster. I have these in my 70 Dart. Being they are 1 year only, they go for BIG bucks !!!!!
