Thanks for the tip Schlud. That info will come in handy for my install.
BTW, I had heard that SLR revised the older shackles with a newer design that takes out the extra space between the shackle and leaf and/or the hangar. Is there any validity to this? I didn't hear of this until after I had ordered them. I was just planning on turning some bushings out of some stainless bar stock I had laying around the shop, or perhaps finding some urathane bushings that I could have made work. I don't know, taking a look at Goth's pic it looks like there is no space there.
