Hey so when I ordered mine the site looked completely different I didn’t have to do all that.. however may not be a bad idea to send sketch.. I just measured out and sent him how long and wide the tank was.. also I measure how far the light mounts were from the edge of each overflow and specified that I was using the ai hms mounts.. and he took care of the rest! I also specified where I wanted cord cutouts which was one on each side and at each back corner but again his site did not look like that before.. sorry if I was not much help
