I bought a used shackle flip from another member and will be instaling it this weekend. My question is how to mount the actual shackle, open or closed side towards the u-bolts? Does it make a difference? I noticed in both the CK5 and OffRoad.com write ups the closed side is toward the u-bolts but the ORD sale page shows the open side toward the u-bolt. I would think the open side is correct but I just want to make sure. Thanks!
