WTB: Coupe seat belt extender arm

[302cid]

Had a friend of mine riding in my car complain that the passenger side seatbelt wasn't acting like the one in his car. Went to go look at it and it seems like the cam in the seat belt extender arm somehow broke. Fordparts.com doesn't sell just the arm, and I really don't feel like paying a boatload for a whole new seat belt assembly. Anyone have one by chance laying around? Perhaps after a harness install or something?

For reference, this is the part I'm talking about

It comes off in literally 30 seconds.

Thanks in advanced

What year and how many miles. Seat belts are covered for longer than the 3/36,000. It's something like 5/60,000.
