I just assembled an S tail you want the easiest way to do it? PICTURES, PICTURES, PICTURES!!!!! Get some zip sandwich bags and tape every screw, bolt, washer small part to the piece its going back in/on!!! Label every bag and picture make sure you take a complete array of pictures to help you!! I would suggest before and after pics honestly! Take a picture, then take the piece off and take another picture!! I know it sounds like a pain but it took me two months and allot of beer and cussing to get the damn tail on!!! Just my opinion!!!
