Yup! Mine were too long too! However, I just got mine in last week when I installed them and it seems to me that SLR has somewhat fixed it for any new purchasers. My lower bolts are about an inch too long, but the bolt is threaded far enough down to not run out and it can be tightened down. It just has a little (about and inch) of threaded bolt that needs to be hacked off. Also, SLR now sends lock-nuts with the shackles too! No trip to Home Depot for anybody else.
