Fancy Stock for The Vulture

Wanted my Vulture build to have the fancy stock, but realized that the back of the Vulture is just slightly different. Narrowed the connection holes to be for the Vulture's M3 hardware (instead of smiley's #6 screws), added spacers to account for the wider installation spot, and cut and extended a few parts to make it work nicely. Still uses the #6 screws for to connect all the stock bits onto the core, but the core attaches to the gun with M3s.
