In the instructions for the skeg installation on an Annapolis Wherry, it indicates that 3 longer #8 screws and 1 shorter #8 should be used. I only find 4-1" #8 screws in the package. Are the "longer #8's" longer than those supplied or is the shorter #8 shorter than those supplied?

Additionally there are a hole bunch of 1" nails in the parts bag but I haven't found any reference to what they are intended for in the instruction book. (I may missed it if there is)

Thanks, Bill from Ottawa
