Concerning the shorter screws, no, they don't come with the contoured heel. I used regular screws, and dremeled about 1/4" off of them (just for the two towards the headstock). Took all of two minutes. If you don't have a dremel, a hacksaw and a vice would work great. You can also get them from the turtle, but you need a $20 order.
