DuBro has the crimp tubing sold alone .. around a dozen pieces in a pack .. they also have the 1" long 44 rod with the hole for the wire in it available alone (if you want a clevise ont he end of the wire)

You don't want to use that 4-40 rod with the hole for the cable, whatever they actually call it. The hole drilled thru it for the cable has a sharp edge that will cut into the cable over time. Better to use 4-40 eye bolts to convert to clevises. Those are also available thru LHS or mail order.
