Seatbelt extenders

I have tried everything suggested but what I need is available only as a bolt-on. The local Ford dealer didn't have it and said they couldn't get it. I sent photos to seatbeltextenderpro.com and they responded, "Unfortunately, there is not an extender available on the market for that exact seat location in your vehicle. I know that is not the news you were hoping to hear, and I'm so sorry to have to share it."

Guess I'll have to lose a few pounds.

Thanks for the input.
