Can i use these 70 charger seats

I have a 1971 Dodge Demon 340 that came with beautiful buckets that i assumed were A body demon/duster but i did research and they are B body buckets. The brand new floor plans have welded brackets and are prepped to be drilled for buckets. The question is will these buckets work in the same bucket seat holes? I dont want to spend several thousand dollars between buying buckets and new covers if these will work.

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 !!!!!

Take a picture from the side, and post a pic here. I will let you know if they are 70 seats.
