Everyone has been guilty of not searching at one point.....Cut 'em a break
I used the stock chevy shackle inbetween my 2nd shackle and the hanger, and made my 2nd shackle 5 1/2" eye to eye. Anything around there will work out pretty well. I know a lot of people don't like doubles, and a lot of people do. So its up to you and hopefully it helps if you do use them.
