I have had these telephone poles laying around for awhile so decided to make a load with them.
To attach the chains I drilled small holes in the top of the car. I took 4 short pieces of 20 gauge solid wire and made a small loop in the end and hook it to the chain. I then put the chain over the poles, stuck the wires through the holes and twisted them together. If the chain was still loose, I used a pair of needle nose pliers and make a kink in the wire to make it tighter.
This was a fun little project that only took a few hours , mostly waiting for the paint to dry.
