G1 Long Haul Grill

Does anyone know why so many of the long Hauls don't have the cut out in his front grill? When I was a kid I remember having to return long hauls because he didn't have the hole. After a while I figured that the pictures were the mistake not the toy. So I cut one where the plastic formed the same shape. Then last weekend at a yard sale I bought a box of TF's and inside was a correct Long Haul. Even the ones I bought as scrap on Ebay all had solid grills.
