Hardware for soft top attachment

I hope that you can help me. I need a source for the actual hardware that the soft top attaches to for a 2001 soft top. The molded flanges that the top slips into before it is tightened. My fractured over time. It seems that everyone will sell replacement tops, but not the hardware. Any help would be appreciated.

I have parts 11, 12 & 13 to secure a soft top for '99-04 Chevy Tracker/Suzuki Vitara for sale
