83 convertible parts help please

[Headhunter]

I am trying to finish this car up but I need a couple of hard to get trim parts. The plastic trim piece that covers the shoulder belt where it comes out of the rear quarter panel is missing on both sides of the car. The car was built in Feb. 1983. I have gone through all of the pony parts people I know. Any help is appreciated. If somone has these and wants to sell them let me know.
Thanks is advance for the help.
