From memory I think most have little repeaters on the front top edge of the rear arch. Always seemed daft because they weren't even at the highest point but I was something to do with measurements from a certain point at the front so the top/middle of rear arch is too far back!! I was going to put some on the side of the scuttle but think there was a reason why it wouldn't pass Iva. No reason not to go with them after Iva though
