Drilling into the fiberglass is done with a sharp drill bit and I like to start with a very small drill first, like a 1/16 then after you have verified that the hole is in the correct location you can move up to the desired size. If the hole is off alittle you can use a 1/8 inch drill to hog it out to the correct location the chase it with your desired drill size. If you need more information just give me a call
