I had the same prob w/ my comptip masthead. The first hole is right in line but the 2nd one comes up a lil short. I contacted my hobie dealer about it and he said to just drill a new hole and pull out one of the sheaths. I decided against that and so i went and picked up two mending plates. I riveted them to the bracket and then drilled the appropriate holes in it. Make sure your local hardware store stocks 3/16 stainless steel bolts. Come to find out lowe's doesn't stock anything lower than a 1/4. In light of finding this out i had to take a titanium drill bit and drill out the steel bushings that fit inside the sheaths. This is a painstakingly long process but in the end it worked out perfect. Have hit the water with it several times w/ no prob. Good luck.
