Hi, I purchased the mast base/foot rebuild kit. The old base hardware was stuck so good, I had to drill the heads off, then grind the remainder flush with the deck. The new base has a different mounting pattern, which is good because I couldn't get the old hardware out. I'm in need of knowing the type of mounting hardware used for this install. I called usSpars and they referred me to sailboatOwners.com....neither could help. Also, if anyone knows how thick the deck is in that area....thanks
