69 dart bucket seats

I would like to change my 69 dart from a bench seat to buckets. I know the seat tracks are specific for an A-body. I have some 69 factory head rests already with chrome bezels that sit on top of the seats. What i would like to know is. will any 68 69 year bucket seat fit in my car?

are charger, roadrunner, dart, barracuda, coronet etc.... seats all the same as far as the seat frames, foam, mounting holes for head rests go? I know they have different covers.
