1975 Duster 318
I just want to post this because it's something I had looked for and couldn't find much info. After several years of purchasing and returning junk seat covers, I finally found one that did the job. This one works for a variety of split bench configurations and fit my '75 Duster 50/50 split back nicely. I had to do a couple of hand stitch repairs and put hog rings on the zippers so they didn't pull apart on me. The back is open and straps exposed, but it's great for the price. Also applied a lot of gorilla tape to the seat beforehand so it will hopefully keep it's shape. Good luck.
