Seat covers

I recently got a decent set of bucket seats given to me from a 71 dart for my 69. I have located seat covers sets however the seats from the 71 have the stitching in different pattern than my 69 has. Has anyone ever used or know if the rear seat cover for a 71 will fit the rear seat of my 69. I'm desperate to get rid of the horribly uncomfortable fiberglass buckets the prior owner installed but would really like the front and rear seats to match.
Thanks
