End link bolts are nothing special. They are just regular bolts. The spacer tubes can be made from 3/8" schedule 40 steel pipe. If you have new bushings and washers, you can source what you need for the spacer and bolt at a hardware store. Mocking up the sway bar and measuring what fits is the best route as everything will be matched to your car. Even the ADDCO links may need some tune-up to fit best on your car. The cost for the parts at the hardware store should be $5 orless.
