Grizzly 550 bullet box part number?

Any one have any idea what the part number is for a ehs bullet box for a 550 I ordered my big three kit and was getting ready to install it and on the side of the package it says grizzly 700 with a line through it and in sharpie its written "duals map" the part number on the package was 1002. I emailed EHS and no reply. Any ideas?
