The original poster was looking for '71 F-body Deluxe shoulder belts.
Those will be made by Hamill & have their own shaped male end.
I have a complete set of '71 Standard Black F-body belts, they are the same style Irvin belts as posted above by RAIVJudge. Am searching through boxed old stock for any '71 Hamill deluxe belts i kept from previous partscars. Have multiple dozens of original early '70's A-body & early 2nd Gen belts. If a mediocre quality seat belt had a rusted pitted male end or buckle, I cut the anchor end off & often threw away the remainder of that belt.

On the Irvin model 2206 part number 9610210 belt dated 13A62, it is not an original F-body belt. Am 100% sure of that, have put a lot of time into restoring my late '72 T/A's seatbelts & am having tags made for them. Late '72 model F-body front & shoulder belts were Irvin 2212 & have a specific style female buckle & male ends. These did NOT share the exploding style small textured buckles used in '73 F-body's.
