SO I could find a car? or slug that will fit my slot, attach the clew to it, and then run it back?
Now I was in the same situation.. none adjustable outhaul. I have a padeye at the end, and a little cleat 12" back up the boom.
Sail should come with a heavy duty slug at the aft end that will fit your boom track. All you need to do is figure out how you want to rig the outhaul - internal or external, 1/2, 2/1 etc.
