djlantis57 - the issue with the heim and the pin is not the "line of thrust", but the fact that the pin is not fixed to the heim and especially the swaybar.
Try this - find a bolt (preferrably with full thread) that fits the hole in the sway bar closely, put it through the hole and pull it tight and the holding the very end of the bolt "wiggle it", I'll bet it moves - now find a nut and run it down the bolt and tighten it down so that the end of the sway bar is held tightly betwene the head of the bolt and the nut - I'll bet you can't wiggle it now!
Think about this now - how much force did it take to wiggle the bolt without the nut? How much force do you think the sway bar exerts?
Jluck - that can work - but if you're going to go that route, then you might as well stick with the OEM style end link, which will outlast the heim. The way I understand it, what we're trying to achieve here is a quick disconnect link - pull the pins and tie the sway bar back, rather than grab two wrenches and unbolt the end link.
