Lancer 28 sliding jib sheet cars

[Paloo]

Hello Lancer owners! I'm looking for the tightening screw that snugs down the jib sheet eyelet that travels on a small track. This part has a black hand grip and screws down into the slider car. Anyone have a spare? Thx...

For my jib sheet leads, I use single blocks with snap-shackles and clip them on the perforated aluminum toe-rail..I seldom have to move them but if necessary, the position can be changed while underway..
