WTB - Original Bimini frame for 82 supra star

[Yama1]

Looking for the original bimini top frame that slides in the current track. I have a new 2 bow frame that I can use/make custom, but would be nice to find a used older one that fits the original. I figured this would be worth a shot at asking before I making other mounts on the boat.

Thanks in advance for any information of where I may find this.

thanks
