I've been thinking of making some shackles for awhile now that would swivel but not unload like a revolver shackle. I was thinking of using a BF Nut and a bolt to match that would be the swivel. My thoughts are with the amount of compression I get out of my leafs I might be able to alleviate some stress by having a pivot point on the shackle. I saw a pic of this done once in a wheeling mag. Can anybody think of a good reason not to attempt this? Anyone think it's a good idea?
