I think I have wrong rear seat - help

In the final stages of my 71 Demon build and I had all my new interior in minus the rear seat assembly. I sent them to get reupholstered and when I attempted to reinstall I noticed it doesnt quite fit correctly. The bottom cushion hooks don't line up and the lower rails push it upward. Can someone share a picture of your bottom cushion frame so I can know what it's supposed to look like. At this point I feel I can just modify this frame to work since I already had it reupholstered.
