What is the distance between the bottom of the lock to the bottom of the hex? I am running into clearance issues with the locks that I have now. They are the ones that came with my scorpian 3/8 narrow body rockers. I am looking for locks that have about 0.060" more height between the bottom of the lock and the bottom of the hex.
