I have a 2014 SCREW that I just ordered the BellTech drop shackles and shims.
I was looking at the instructions on line (http://www.belltech.com/extras/docs/BBGC/6700.pdf
) and it shows that the shackles get installed in the opposite direction from the OEM shackles (OEM has open part to the back, Belltech shows open part to the front). Is that correct?
Also it references having to modify the seam under the bed, did you do that?
