Hi, I know this is an old thread...... I am using a pair of '67 seats for my F100 project and all of my roller bearing retainer clips were broken or missing.....
I have two pair of seats and I am only using one pair for the truck. I have some extra seat tracks but all of the nylon clips are broken.
I was looking into having those nylon clips made from a 3D model i made. They work out to about $9 each but worth it as the seats won't work that well without.
Is this what you are looking for? I could more add to my order and maybe bring the price down a bit. LMK
