Swinger Front Bench Help

Hello. After looking and failing, and not taking better photos before disassembly, I am here for some guidance. This is a 70 Dart Swinger with a front split bench seat. I have all my anchor points accounted for but after looking back at the photos I do have, not sure how the belts are routed through the seat. The top of the seat was all but destroyed. Any help would greatly appreciated!!
