If you remove the plate and cleat you will notice the rear leg is a little longer then the two front legs of the fairlead. You need to add washers to compensate for the removal of the plate.

Another nice way to convert the existing sliders is to cut of the front leg of the fairlead after removing the plate and cleat. When you file the front of the remaining U, containing the knob and spring, carefully to a nice rounded shape it will look as if designed that way by the manufacturer. Then use a Harken 2652 which has a clip pitch (32 mm) equal to the distance of the now unused screw holes in the slider. The rear of the Harken clip fits nicely under the remaining part of the fairlead but you may want to add a washer to fill up the gap to the same thickness as the plate that used to be there. while the back of the Harken clip is fixed with the existing screw, the front of the clip is fixed with the old screw cut and filed to the required length and a locking nut. You could use a new, shorter screw but you still would have to file it plane with the top of the lock-nut as you would not want any sharp parts there, trying to pinch a hole in your clothes.[attachment=1:300xiner]fix.jpg[/attachment:300xiner] Obviously other brands can be used too but I have used Harken and I know it fits from experience.

Here is what my thwart looks like: [attachment=0:300xiner]thwart.jpg[/attachment:300xiner] The set-up is made with a Harken 2640 – 40 mm ratchet cheek block on a slightly angled, well painted piece of plywood. The swivel cleat is a Harken 240 (or is it a 241?). A swivel is nice for single handed sailing, a simple cleat on a pedestal should be good enough for a two person crew.
