71 Duster Bucket Seat Vs 72 Duster Bucket Seats

Ok here’s my problem. I need 71 Duster bucket seats. What I thought was 70 bucket seat frames, I now find out I have 72 Duster seats which was a one year only where the back parts of the bucket seats have the springs molded into the foam. I got that info from Ron at Legendary Upholster and he told me no one is making new seat foam for 72 buckets. So Im now searching for 71 Bucket seats. Used is ok but I see them new too n if I have to bite the bullet I’ll buy new. Anyone ever buy new 71 frames or any leads on used ?
Thanks
