I'm finishing the RV12 tail kit and I'm on 11-04 step 4. It calls for me to twist safety wire around the hinge pin ends. There are tiny holes provided in the HS to run wire through. What size wire do I order? There isn't any with the kit. Also, do I need to order the twist pliers? And, should I order extra in case it is needed later? I'm assuming I should order SS rather than brass. Thanks for the help. Rob
