have a set of shackles that measure 7" from eye to eye. would work good for a 52" spring swap. i just decided to go with some 7 1/4" shackles from BWP. i bought these from ORD, then i cleaned them up, threw on 2 coats of primer, then threw on 2 coats of gloss black paint. there's pictures of them on my buildup thread on my sig. if you're not internet savy, let me know & i'll post up a pic as soon as i get a chance. $45 shipped.
