Fold down rear seat

Got a good deal on a fold down rear seat for my '69 Barracuda. Is it a simple bolt in on a non fold down car?
It has hinges on either side and looks like shims on the flat part of the hinges.
I know that I am going to have to change the seat back with my upholstery, but other than that will bolt in to my existing configuration.
Thanks, Pete.
You can move the needed parts over to you old seat back, very easy.
