seat tracks
 

I am disassembling my seat tracks to have them zinc plated and the lever to adjust the seat is attached to the track by a large rivet similar to one on a hood hinge. I can grind it off but does anyone know where these rivets can be purchased?

Aren't those tracks available in repo? Would be way easier than trying to rebuild them.

I've never seen them listed for 73-77 Grand Prix. I am doing some modifying anyway so it wouldn't pay to get new ones.
