The only holes that are staggered on the 66 are the outer ones. These are in the section that gets cut off to make it the right length for a 65. All the holes that are left are in a perfect straight line.
Looking at KitCarlson's photos, I can't see how the holes line up on a 65 and 66. The 66 seal is a U shape while the 65 is a L. 66 fasteners are staggered while 65 is straight across. What am i missing?
