has anyone made a clutch for adjusting rod?

Ok I like your ideas the first one could work if once the hole was drilled it was thin enough to go over the z bar but remember the z bar has that little button or knob that the spoon end has to fit over then needs the flat clip to hold it, your second idea could work if I modified the z bar but I don't want to do that as they are hard enough to find as it is and I want to basically keep it stock so I will put it together properly after next week and I locate a proper rod, I have a friend with a US post box that goes across the boarder once every couple months so I will probably just order the proper kit from Brewers and get them to pick it up in the fall, this just needs to last until October when the car sleeps for the winter. I know where I can find one of those ends in your first picture locally in fact I think I can even get one through my own wholesalers at my marine store so I might pick one of those up in case the turn buckle doesn't work as that would at least give me full adjustment on the rod, thanks for all your help.
